Sir George Alexander Drummond, KCMG CVO (11 October 1829 – 2 February 1910) was a Scottish-Canadian businessman and senator.

Born in 1829 at Edinburgh, he was a younger son of the entrepreneurial stonemason, building contractor and city councillor, George Drummond, by his wife Margaret Pringle (b.c.1790).

He helped found the St. Margaret's Home for Incurables in 1894, purchasing the house that had previously been built for Sir William Collis Meredith.

As a member of the Citizen's League, he sought to improve life in Montreal, and he served as president of the Royal Edward Institute, a dispensary for the prevention of tuberculosis, founded in 1909 by Jeffrey Hale Burland (1861–1914).

They also kept a summer home (Gads Hill) at Cacouna, Quebec and an estate (Huntlywood), in the part of the Island of Montreal now known as Beaconsfield, where they raised pure-breds and kept a private golf course for their friends.
