Kunsthalle Bielefeld, Art museum and architectural monument in Bielefeld-Mitte, Germany.

Kunsthalle Bielefeld is a modern and contemporary art museum on the south-west edge of Bielefeld's old town. Philip Johnson designed the cubic building, erected in 1968 by Cäsar Pinnau in the International Style; it is Johnson's only museum building in Europe. Its facade is clad in red sandstone, and the upper volume overhangs a recessed glazed entrance level carried on three tall rectangular piers. It has three storeys above ground and two below, with 1,200 square metres of exhibition space.

The building was designed in 1968 by American architect Philip Johnson and was his only museum project in Europe. It owes its existence to businessman Rudolf-August Oetker's art collection and patronage, who created an institution for modern art in his hometown.

The name refers not to Oetker but to a dispute: he wanted it called Richard-Kaselowsky-Haus after his stepfather, a former NSDAP member. Protests and cancellations marked the silent opening on 27 September 1968, and the city later dropped the name. The collection focuses on Expressionism, international sculpture and contemporary art, with Picasso, Max Beckmann and the Blaue Reiter.

The building sits on the south-west edge of Bielefeld's old town, beside a paved square with trees. Inside are a shop, a café and a library, and guided tours and teaching activities for all ages supplement the exhibitions. The sculpture garden, laid out in 2008 to Johnson's 1968 plans, holds Rodin's Thinker and Serra's Axis in front of the entrance.

Philip Johnson's only museum building in Europe was nearly joined by a Frank Gehry deconstructivist extension in 1994, meant to link it with the neighbouring natural history museum. Maja Oetker, wife of Rudolf-August Oetker, opposed it so firmly that the plan was dropped; Gehry instead built the Marta museum in Herford, 15 km away.
