Bierpinsel (or Beer Brush) is the name of a building with a restaurant in the Steglitz neighborhood of Berlin. It has a height of 46 meters with a shape resembling that of an observation tower - the original architectural idea was that of a tree shape. It was built from 1972 to 1976.

The building has three floors usually equipped with restaurants and a night club. The history of business usage is long and filled with bankruptcy featuring short periods of closing the building. In 2002 the building was sold as it required costly reconstruction. The location is very prominent at the metro station Schlossstrasse and highway exit Filandastrasse close to the Steglitzer Kreisel shopping center.

The Bierpinsel is closed (since April 2006). The new owner wants to rebuild the complete area with a new entrance building. The plans have been criticized as it shall also rework the tower restaurant - a golden exterior will probably destroy the traditional pop-art impression that made it famous. Likewise the name shall change back to a neutral variant - the building had opened first as "Turmrestaurant Steglitz".

Starting in April 2010, several prominent graffiti artists painted the exterior of the structure over several weeks, as part of the Turmkunst (Tower art) 2010 project - an exhibition of street-art taking place both in and around the tower.
