David Henry Drummond (11 February 1890–13 June 1965) was an Australian politician and farmer.

He was a member of the Country Party and served in both the New South Wales Legislative Assembly (1920–1949) and the Australian House of Representatives (1949–1963).

He was the fourth son born to Catherine (née McMillan) and Morris Cook Drummond; his parents had immigrated from Scotland.

[1] Drummond's parents died when he was a small child – his mother in 1892 and his father in 1896 – leaving him an orphan.

In 1949, Drummond switched to federal politics and was elected to the House of Representatives seat of New England.
