Amelia is an opera in two acts by Daron Hagen to a libretto in English by Gardner McFall based on a story by Stephen Wadsworth. It had its world premiere at the Seattle Opera on May 8, 2010.

In 2007 Amelia became Seattle Opera's first new commission in 25 years. The Andrew W. Mellon Foundation issued a grant of $500,000 in 2009 to underwrite the first two revivals of the world premiere production.
