Sir Andrew Thomas Taylor, JP, RCA, FSA, FRIBA (13 October 1850 – 5 December 1937) was a British architect and councillor.

In 1864 he began his architectural training as an articled apprentice to Pilkington & Bell in Edinburgh, staying for five years.

His essay on London's 16th-century architecture won a Royal Institute of British Architects (RIBA) silver medal in 1874.

He subsequently published a book on the subject: The Towers and Steeples designed by Sir Christopher Wren, a descriptive, historical and critical essay.

[1] In 1879 he established his own architectural practice in London, with a design for a Memorial Hall and Schools at Dover being his first commission (completed 1881, since demolished).

Together with Henry Hall, another of Pilkington's former pupils, Taylor entered the competition to design Glasgow City Chambers, being placed second.

Taylor performed alterations and restoration on the Christ Church Cathedral from 1890–91, and installed a memorial window for Mrs. A.C. Hooper, 1902–03.
