Isla de Janitzio (Spanish pronunciation: [xaˈnitsjo]) is the largest of five islands in Lake Pátzcuaro in the state of Michoacán, Mexico.

[1] The town of Janitzio, which means "maize flower" in Purépecha[citation needed], is located atop a hill on the island.

The town is known for the butterfly fishermen who are skilled at lowering their butterfly-shaped nets to catch "pescado blanco" (Chirostoma estor),[4] a species of freshwater silverside endemic to the lake which is important to the local cuisine.

A 40-meter statue of José María Morelos, a great hero of Mexico's independence, started in 1933, is found on the island's highest point.

Along the interior walls, the life of Morelos is depicted in murals painted by Ramón Alba de la Canal and other Mexican muralists.
