Auguste Charles Philippe Robert Landry (15 January 1846 – 20 December 1919) was a Canadian parliamentarian who served as Speaker of the Senate of Canada from 1911 to 1916.

[citation needed] After the 1911 federal election brought the Conservatives into power after a fifteen-year absence, the new prime minister, Robert Laird Borden, appointed Landry to be Speaker of the Senate.

[3] Landry was a prolific author and editor who wrote a number of books on matters of public policy in addition to his writings on agriculture.

[4] His interests in these questions made him a controversial figure as Speaker when the Senate was considering the issue of francophone schools in Ontario in the wake of the provincial Conservative government's passage of Regulation 17 which restricted French-language instruction.

He remained a Senator until his death three years later in Quebec City and devoted much of his time writing and campaigning on the issue of French-language rights in Ontario.
