Globally, Leissa (Leissa 
) is a rare feminine given name. The forename Leissa is characteristic of the Democratic Republic of the Congo, where it is a rare feminine name, Australia, and the United States, where it is a very rare principally female, but scarcely masculine name. Measured by absolute frequency, it most frequently occurs in the Democratic Republic of the Congo, the United States, and Brazil. Very seldom, Leissa is the last name as well as the forename.
