hockey play in the United Collegiate Hockey Conference.
The women's ice hockey team was the first NCAA women's ice hockey team in Pennsylvania.
Chatham athletics announced in November 2024 that they will be adding a Co-ed competitive cheerleading team for the 2025-2026 season.
The college mascot was previously Pennsy the Seal. The cougar mascot was adopted in 1992 and was named Carson in honor of alumna Rachel Carson in 2011. In 2023, 55.6% of students participating in a non-binding referendum held by the student government voted to reinstate Pennsy the Seal as the college mascot. The vote did not affect the college mascot. In a later April 2025 referendum, 60% of students who participated voted in favor of reinstating Pennsy the Seal.
