Lambert Fieldhouse is an athletic facility on the campus of Purdue University in West Lafayette, Indiana.

It was built in 1937 on land bought by David Ross and George Ade (the namesakes of nearby Ross–Ade Stadium) as a replacement for Memorial Gymnasium to be the home of the Purdue basketball team, and also contained an indoor track.

In 1967, the team moved into the newly built Mackey Arena next door, and the building was remodeled to become a full-time track facility.

The building also contains pool facilities, which were in use by the swimming and diving teams until 2001, when the Boilermaker Aquatic Center was completed.

The academic portion of the building lacks handicapped accessibility to most offices, classrooms, and laboratories and possesses an antiquated heating/cooling system that results in stifling work conditions during summer months.
