〈希腊古瓮颂〉（英语：Ode on a Grecian Urn）是英国浪漫诗人约翰·济慈的诗作，作于1819年5月，1820年1月出版。它与〈怠惰颂〉、〈忧郁颂〉、〈夜莺颂〉、〈赛姬颂〉和〈秋颂〉并称为济慈传世的六大颂诗。在创作晚期，济慈不满足于早期诗歌体例，于是发展出全新的颂体，即以他的六首诗为代表。他在阅读英国作家及画家本杰明·罗伯特·海登的二篇文章后，灵感泉涌而提笔写下此诗。济慈十分喜爱古希腊艺术作品，曾以埃尔金石雕之名作诗；他对古希腊艺术的理想主义哲学的信仰，以及对希腊古风之美的刻画，构成了此诗的基础。

"Ode on a Grecian Urn" is a poem written by the English Romantic poet John Keats in May 1819 and published anonymously in the January 1820, Number 15 issue of the magazine Annals of the Fine Arts (see 1820 in poetry).

The poem is one of several "Great Odes of 1819", which include "Ode on Indolence", "Ode on Melancholy", "Ode to a Nightingale", and "Ode to Psyche". Keats found earlier forms of poetry unsatisfactory for his purpose, and the collection represented a new development of the ode form. He was inspired to write the poem after reading two articles by English artist and writer Benjamin Haydon. Keats was aware of other works on classical Greek art, and had first-hand exposure to the Elgin Marbles, all of which reinforced his belief that classical Greek art was idealistic and captured Greek virtues, which forms the basis of the poem.
