To narrow down the question, we could consider:
* The most influential poets: William Shakespeare, John Milton, William Blake, William Wordsworth, and Alfred Lord Tennyson, among others, have shaped the course of English poetry.
* Poets who are considered the best: This is highly subjective, but many would include poets like T.S. Eliot, W.B. Yeats, Sylvia Plath, and Seamus Heaney.
* The most popular poets: This could vary depending on the time period and audience, but poets like Robert Frost, Langston Hughes, and Maya Angelou are well-loved and widely read.
Instead of asking "who" is the poet, it might be more helpful to ask:
* What kind of poetry are you interested in? Romantic, Victorian, modernist, contemporary?
* What themes are you interested in? Love, nature, politics, social justice?
* Who are your favorite poets already? Their work can lead you to other poets you might enjoy.
