David Gilpin JP (6 April 1863 – 21 May 1952), was an Australian schoolteacher, businessman, accountant and local government politician who served two terms as Lord Mayor of Sydney and was the last Mayor of Camperdown, leading the negotiations that led to Camperdown Council's amalgamation with the City of Sydney in 1908.

[1] David Gilpin was born on 6 April 1863 at Carlisle, Cumberland, England, and emigrated to Australia aged 3 with his parents in 1866, arriving in Brisbane before moving to Sydney in 1867.

[11] Joining the Civic Reform Association when it was created, Gilpin became honorary secretary and was elected Lord Mayor of Sydney for 1923 and 1924.

[15] However, when the Water Board was reconstituted in March 1925 shortly after as an elected, rather than appointed body, Gilpin, who now lived in Burwood, stood for election and was successful for the Fifth Constituency (Annandale, Ashfield, Burwood, Concord, Enfield, Glebe, Homebush, Leichhardt, Lidcombe, and Strathfield).

[17][18] Gilpin's wife, Mary Ann, died at their residence, "Kayla", on Parkes Street, Wentworth Falls on 5 November 1938.
