The Ubbo-Emmius-Gymnasium is a gymnasium in the town of Leer in Lower Saxony, Germany.

The Ubbo-Emmius-Gymnasium was founded in 1584 as a High School for boys only and girls were not accepted before 1972.

It was named after Ubbo Emmius, who was principal at the former Latin school from 1588 to 1596, today being the Ubbo-Emmius-Gymnasium.

In 1998, a small separate building with six classrooms was established on the school grounds.

A close cooperation exists to the second Gymnasium in Leer, the Teletta-Groß-Gymnasium.
