Dwyer Arena, officially named Robert and Concetta Dwyer Arena, is a 2,100-seat hockey rink in Niagara University's campus (Lewiston, New York, USA).
It is home to the Niagara Purple Eagles men's and women's ice hockey teams, which play in Atlantic Hockey and College Hockey America respectively. It includes a practice rink.
The building was built in 1996. Prior to the 1999-00 season, major renovation took place as a result of a gift by Bob and Connie Dwyer, both 1965 graduates, who contributed $3 million for facilities upgrades. Locker and training rooms, player's lounge and lobby were upgraded, while separate entrances for the main and auxiliary rinks, new pro shop and new ticket office were arranged. In the summer of 2007 a Premium Seating Section was added in the area formerly occupied by the Party Deck, and as a result, capacity was increased from 1,600 to 2,100.
It hosted the College Hockey America 2002, 2008 and 2010 men's conference tournaments and the 2004 and 2008 women's conference tournaments.
It has been home of the Buffalo Sabres Summer Development Camp in 2008, 2009 and 2010.
The arena co-hosted the 2011 World Junior Ice Hockey Championships.
