Leaf Hall is a grade II listed former working men's institute in Eastbourne, East Sussex.

It was built in 1863–64 to a design by Robert Knott Blessley in a continental gothic style for the philanthropist William Leaf.

The foundation stone stated the building's purpose was "to promote the social, moral and spiritual welfare of the working classes of Eastbourne".

In the absence of a local theatre the hall was used for staging visiting shows, including General Tom Thumb in 1865.
