Kaffeehaus am Emmasee, Protected cultural heritage building in Schwachhausen district, Bremen, Germany.

Kaffeehaus am Emmasee is a cubic, one- to two-storey café built from 1963 to 1964 by Hans Budde and Carsten Schröck, standing in the Emmasee in Bremen's Bürgerpark near the animal enclosures. Its three square pavilions, each 8 m × 8 m, have ceilings carried by a single central mushroom column, and the building appears to float above the water.

The building was designed by Heinrich Müller in 1867 as a modest wooden structure on Emma Lake and underwent expansion in 1874 to accommodate growing numbers of visitors. This early enlargement reflects how quickly the Bürgerpark area gained popularity as a leisure destination.

The house is named after Countess Emma of Lesum (c. 975/980–1038), who according to legend gave Bremen the pasture that became the Bürgerweide in 1032. After a 2010 renovation it reopened as "emma am see".

The building stands in the Emmasee itself, near the animal enclosures in the Bürgerpark, so it is reached on foot through the park; the upper floor was added in 1969. After a 2010 renovation it reopened as "emma am see".

The 1963–64 building by Hans Budde and Carsten Schröck stands in the Emmasee itself, not on its shore, so water is visible from inside and outside and the house seems to float. It won the BDA-Preis in 1974; the upper floor was added in 1969.
