The tall ship Elissa is a three-masted barque. She is based in Galveston, Texas, and is one of the oldest ships sailing today. Launched in 1877, she is now a museum ship at the Texas Seaport Museum. She was designated a National Historic Landmark in 1990. The Texas Legislature designated Elissa the official tall ship of Texas in 2005.

A tall ship is a large, traditionally-rigged sailing vessel. Popular modern tall ship rigs include topsail schooners, brigantines, brigs and barques. "Tall ship" can also be defined more specifically by an organization, such as for a race or festival.
