The criterion for this list is not greatness in the abstract — though most of these books are great — but influence: what did this collection make possible that was not possible before it? Which books shifted the terms of what poetry was allowed to be, who was allowed to write it, and how it was allowed to look on the page? The answers are sometimes surprising. Lowell's Life Studies is the obvious choice for the confessional tradition; I've left it off because what Plath did with that tradition is both more radical and more influential on what followed. Mary Oliver is not here, not because her work doesn't matter but because she changed how many people read poetry rather than changing how poets read it. The distinction matters for this particular argument.
A caveat: influence is not the same as quality, and several books on this list are more important than they are enjoyable to read. Note which is which.
The argument for Ariel is not that it invented confessional poetry — Lowell did that — but that it made the first person dangerous again. Plath's "I" is not the reticent, self-doubting speaker of earlier American confessionalism; it is a speaker who knows she is performing and performs anyway, with a theatrical intensity that veers between the comic and the terrifying. "Lady Lazarus," "Daddy," "Ariel" itself — these poems changed what was permissible in tone. The irony, the fury, the refusal to apologise for extremity. Every poet who has used the first person for dark material since 1965 is reckoning with what Plath showed was possible. See also our introduction to Plath's work.
Berryman over Lowell is the contentious choice on this list, and I'll defend it: The Dream Songs made fragmentation a structural argument rather than an aesthetic preference. The sequence as a form that couldn't be shuffled — that required reading in full to yield its meaning — is something The Dream Songs demonstrated at length before almost anyone else. Henry, the speaker-who-is-not-the-poet, the third person and the first person and the minstrel persona colliding across 385 poems: this is the sequence as a total work, and it changed what the long poem could be. The comic mode in the service of the tragic, without the comedy softening anything — that is also Berryman's specific contribution, and it is everywhere in contemporary poetry.
What Rich did in Diving into the Wreck was demonstrate that the political poem did not have to sacrifice the lyric. The title poem is the example everyone cites, and for good reason: it is both a sustained argument about gender, power, and what we have inherited, and a genuinely strange, beautiful lyric experience. The book changed what poetry was allowed to be angry about. Before it, feminist anger in poetry tended to be marginalised as polemic; after it, the political lyric was a legitimate and serious mode. The influence runs in every direction — through the next generation of feminist poets, through the documentary poem, through every poet who has tried to make the political intimate without making it merely personal.
Citizen is the most formally disruptive book on this list because it is not, by most definitions, a book of poems. It contains poems, but also prose, essays, image sequences, and what might be called documentary fragments. Rankine dissolved the boundary between the lyric and the documentary, between poetry and criticism, between the personal and the structural. The result was a book that could be read as poetry, as cultural criticism, and as testimony — and that performed the experience it described rather than simply reporting on it. Everything published since 2014 that tries to work across genre, to use the lyric for documentary purposes, to implicate the reader in what the text is doing, is working in the space Citizen opened.
Carson proved the long poem wasn't dead — it just needed to stop apologising for being long. Autobiography of Red is a novel in verse, a reimagining of the Greek myth of Geryon and Herakles as a contemporary queer love story, a meditation on perception and desire and the relationship between image and fact. It is also very long, and unapologetically so: it takes the time it needs. In a literary culture that was — and still largely is — suspicious of ambitious formal projects, Carson's refusal to compress gave permission to an entire generation of poets to think at scale. The influence runs through every contemporary poet who has attempted the book-length lyric, the verse novel, or the hybrid long poem.
The underrated entry on this list. Derricotte's Tender is less famous than the books around it and more quietly influential than its reputation suggests. It pushed into territory — the body, the psychology of race, the interior of shame and its relationship to desire — that American poetry had largely avoided, and it did so with a formal directness that made the avoidance visible. Derricotte is one of the founders of Cave Canem, the organisation that has done more than any other in the past thirty years to support Black poets in America; her influence runs through the poets who came through that organisation as much as through her own books. The book that changed how we talk about witness and interiority in the American lyric deserves to be better known.
Formally the most adventurous book of the last twenty years. Jess writes about the ragtime and early jazz musicians of the early twentieth century in sonnets that can be read individually, sequentially, or in multiple directions simultaneously — across the page, in combination with other poems, according to a diagram. The book is about polyphony: multiple voices sounding at once. Its form enacts that polyphony structurally. A Pulitzer Prize winner that demonstrates formal radicalism and popular recognition are not mutually exclusive. What Olio changed was our understanding of what the page can do — how a poem can be an architecture rather than a sequence, a space rather than a line. It belongs in the conversation about what the sonnet can still become. See also our list of contemporary poets worth reading.
The first book by a poet of Vuong's generation to reach a genuinely mass readership without simplifying itself. This matters as a cultural fact independent of the book's considerable qualities: Vuong demonstrated that formally serious, emotionally demanding poetry could find a large contemporary audience. The inheritance of war, the body under pressure, language as both shelter and weapon — these are not soft subjects, and Vuong does not handle them softly. The book also reintroduced tenderness as a serious poetic mode, at a moment when tenderness had been largely evacuated from the contemporary lyric in favour of irony. For a full account, see our introduction to Vuong's poetry.
Elegy was exhausted until Smith found a new thing to mourn and a new velocity to mourn it at. Don't Call Us Dead mourns Black men killed by police and by AIDS with a formal range — lyric, list, incantation, elegy, something approaching liturgy — that had no real precedent. What it changed was the elegy's permitted emotional register: Smith's elegies are furious as well as grieving, political as well as personal, and they refuse the consolatory arc that the genre had typically provided. After Smith, the elegy as a mode of witness — rather than primarily a mode of consolation — became available in ways it hadn't been before.
Long Soldier responds to the United States government's 2009 apology to Native peoples — issued without ceremony, without the presence of the people it addressed — by making the language of official apology into a lyric form. The legal document, the government resolution, the formal "whereas" clause: these become the material out of which genuinely devastating poetry is made. What WHEREAS changed is the relationship between form and politics in poetry: it demonstrated that the most formally inventive choice can also be the most politically necessary one, that the two are not in tension but are in fact the same thing. It also changed what we thought documentary poetry could do — not observe the political but inhabit it, inhabit its language, and find the human voice trapped inside the official one.
