Sir Pierre-Amand Landry, KC (May 1, 1846 – July 28, 1916) was an Acadian lawyer, judge and political figure in New Brunswick.

He represented Kent in the House of Commons of Canada from 1883 to 1890 as a Conservative member.

He taught school for a time, articled in the law office of Albert James Smith and was called to the bar in 1871, becoming the first Acadian lawyer in the province.

Landry served in the province's Executive Council as Commissioner of Public Works from 1878 to 1882 and provincial secretary from 1882 to 1883.

Landry was elected to the House of Commons in an 1883 by-election after Gilbert-Anselme Girouard accepted the position of customs collector.
