Édouard-Louis Pacaud, QC (January 20, 1815 – November 18, 1889) was a Quebec lawyer and political figure.

Pacaud was educated at the Séminaire de Nicolet, then studied law with Antoine Polette at Trois-Rivières, was admitted to the bar in 1836 and set up practice there.

He did not take part in the Lower Canada Rebellion although he did win the release of Louis-Joseph Papineau's brother André-Augustin.

Pacaud was bankruptcy commissioner for Trois-Rivières district from 1844 to 1850, which also required him to preside at the Court of Quarter Sessions and to serve as justice of the peace.

Pacaud ran unsuccessfully for a seat in the Legislative Assembly for the Province of Canada in Mégantic in an 1850 by-election and in Nicolet in 1851.
