Athletics at Oswego have always been a vital part of campus life, and the Lakers' outstanding competitive facilities have served the athletics program well.

Oswego's primary indoor facility is Laker Hall, built in 1968, which serves as the home of the Oswego State athletic department. Within Laker Hall is the 3,500-seat Max Ziel Gymnasium, named for the Lakers' former department chair and coach. The Max Ziel gym hosts men's and women's basketball, women's volleyball, and men's wrestling. This gymnasium has three full-length basketball courts that can be used for volleyball. Laker Hall also includes an auxiliary gym used by many Oswego State programs.

Laker Hall also contains Laker Pool, which is complete with six lanes and separate diving well. The Oswego State wrestling program has a 40-foot by 80-foot practice area with two regulation practice circles. A newly renovated weight training room with expanded workout facilties and equipment for the varsity teams opened at the start of the 2008-09 year to service the college's commitment to the well-being and readiness of student-athletes. Laker Hall also hosts recreational facilities for racquetball and squash.

The convocation center/ice arena in the brand-new Campus Center hosts the men's and women's ice hockey programs. This state-of-the-art facility opened in October 2006. The Campus Center complex represents the new social hub of campus, connecting with renovated Swetman and Poucher halls.

Oswego's outdoor facilities are extensive. The Laker Field complex adjacent to Laker Hall and Romney Fieldhouse includes game and practice fields for baseball, softball, track and field, field hockey, soccer, and lacrosse. It also includes six tennis courts used by both the men's and women's programs.
