Terra Chã (English: low land) is a civil parish in the municipality of Angra do Heroísmo on the island of Terceira in the Portuguese Azores. The population in 2011 was 2,915, in an area of 10.07 km2. Part of the suburban beltway of Angra, the ecumenical parish (São Pedro) was established by King John VI, who granted it a charter on 6 September 1825, but its borders and administrative organs were confirmed by act of the Civil Governor of Angra ten years later on 26 November 1835. However, according to the testament of Pero Anes do Canto, its establishment as a parish dates back to the 15th century.
