Julien de Lallande (Lalande) Poydras (April 3, 1740 – June 23, 1824) was a French American merchant, planter, financier, poet, educator and political leader who served as Delegate from the Territory of Orleans to the U.S. House of Representatives from 1809 to 1811.

He invested in real estate, buying and selling plantations and retaining some major properties for the cultivation of cotton and sugar cane.

He built a number of structures during the late 18th and early 19th centuries, including North Bend plantation house, in 1835, on False River, and owned properties in New Orleans.

The conspirators, who evidence shows to have been urged on by white Jacobin-minded immigrants,[citation needed] were quickly apprehended and several were executed.

Fearful of its consequences, the Louisiana State Legislature prohibited any manumissions, and Poydras's slaves remained in bondage until Union troops entered Pointe Coupee Parish in connection with the Siege of Port Hudson in 1863 — an additional 14 years.

He served in a number of community offices in Pointe Coupee, including the post of civil commandant (under Spanish rule), justice of the peace and church warden.

One of Julien Poydras's more unusual bequests was for dowries of indigent brides in Pointe Coupee and West Baton Rouge Parishes.

Legend attributes Julien's lifelong single status to the inability of his fiancée's family to provide the usual dowry in order for them to marry.

The latter, built in 1924, is now home to the Julien Poydras Museum and Cultural Center, a project of the Pointe Coupee Parish Historical Society.
