James Souttar FRIBA (11 February 1840, in London – 22 April 1922, in Aberdeen) was a Scottish architect. The son of William Souttar, of Edenville, Aberdeen, Souttar worked in Sweden from 1863 to 1866, first at Gothenburg (in 1863) and later at Stockholm (1863–1866). His works there include St Peter and St Sigfrid's Church in Stockholm, known locally as the "English Church", which was moved, stone by stone, to its present location in the Östermalm area of the city in 1913. In 1898, Souttar became the founding president of The Aberdeen Society of Architects.
