St Peter's Church is the parish church of the village of Petersham in the London Borough of Richmond upon Thames. It is part of the Diocese of Southwark in the Church of England. The main body of the church building dates from the 16th century, although parts of the chancel date from the 13th century, and evidence in Domesday Book suggests that there may have been a church on the site in Saxon times. Nikolaus Pevsner and Bridget Cherry describe it as a "church of uncommon charm... [whose] interior is well preserved in its pre-Victorian state". The church, which is Grade II* listed, includes Georgian box pews, a two-decker pulpit made in 1796, and a display of the royal arms of the House of Hanover, installed in 1810. Its classical organ was installed at the south end in late 2009 by the Swiss builders Manufacture d'Orgues St Martin of Neuchâtel, and a separate parish room was added in 2018. Many notable people are buried in the churchyard, which includes some Grade II-listed tombs.
