Georges-Casimir Dessaulles (September 29, 1827 – April 19, 1930), was a Canadian businessman, statesman and senator.

Dessaulles was one of the oldest serving politicians ever, only surpassed by Giovanni Battista Borea d'Olmo.

Dessaulles attended college at Georgetown University where he was a member of the Philodemic Society, graduating in 1848.

[citation needed] Dessaulles is also renowned for only having spoken twice while serving as a Senator.

Once to deny that his appointment was part of a corrupt bargain, and a second time to thank his fellow senators for his portrait, on his 100th birthday.
