18 Poems is a book of poetry written by the Welsh poet Dylan Thomas, published in 1934 as the winner of a contest sponsored by Sunday Referee. His first book, 18 Poems, introduced Thomas's new and distinctive style of poetry. This was characterised by tightly metered, rhyming verse and an impassioned tone. Written in his "womb- tomb period", the poems explore dark themes of love, death and birth, employing a rich combination of sexual connotations and religious symbolism. The lyricism and intensity of the poems in the book contrasted with the emotional restraint shown in the poetry of the successful modernist poets that worked as his contemporaries. The book received critical acclaim, but was not initially commercially successful.
