Peter George Patmore (baptized 1786; died 1855) was an English periodical writer active between the years of 1820 and 1825, known mainly for a series of articles in the New Monthly Magazine entitled "Picture Galleries of England", acting as a critical guide to the main aristocratic collections of Old Master paintings at the time. These articles were a response to, and in some ways a dialogue with, a similar series begun by the great critic William Hazlitt at around the same time, and published in the London Magazine. Patmore's works were serialised and published in a single volume in 1824, of which a copy is available in the Bodleian Library in Oxford. He was forced into publication by the announcement of several other works of the same name attempting to capitalise on his (or possibly Hazlitt's) success.
Patmore was Assistant Secretary of the Surrey Institution, where Hazlitt lectured in 1818, after which the two became personal friends. Patmore was thereby enabled to record many details about Hazlitt later drawn upon by the latter's biographers.
He was also the father of the minor Victorian poet Coventry Patmore.
