Jacques Guillaume Lucien Amans (1801–1888) was a French neoclassical portrait painter working in New Orleans in the 1840s and 1850s.

In 1856, Louisiana planter Robert Ruffin Barrow Sr. persuaded Amans to remain in Louisiana longer to paint an almost life-sized portrait of his wife, Volumnia Washington Hunley Barrow, sister of Confederate submarine captain Horace Hunley, and their daughter, Volumnia Roberta.

The portrait now hangs in Residence Plantation House on Volumnia Farm in Terrebonne Parish, Louisiana.

[2] Influenced by the French neoclassical artists Jean Auguste Dominique Ingres and Jacques-Louis David, Amans emphasized meticulous draftsmanship and realism with particular attention to the sitter’s face and hands.

Among Amans' most famous subjects was President Andrew Jackson, who sat for his portrait in 1840 (the 25th Anniversary of the Battle of New Orleans).
