Dey's Arena, also known as Dey Brothers Rink, Dey's Skating Rink and The Arena, were a series of ice rinks and arenas located in Ottawa, Ontario, that hold importance in the early development of the organized sport of ice hockey in Canada. It was the home arena of the Ottawa Hockey Club, variously known as the Generals, the Silver Seven and the Senators from the 1890s until 1923, although it is known that games were also played at the Rideau Skating Rink in the 1890s and the Aberdeen Pavilion in 1904. The rink and arenas were built by two generations of the Dey family, who were prominent in Ottawa at the time, with a thriving boat works business serving the lumber business. The Dey family also played hockey.

The Rideau Skating Rink was an indoor skating and curling facility located in Ottawa, Ontario, Canada. Consisting of a curling rink and a skating rink, it was one of the first indoor rinks in Canada. The Rideau Rink was scheduled to open on January 10, 1889, but unseasonably mild weather postponed the grand opening to February 1. It opened on January 25, 1889 for select V.I.P.s although this was a misunderstanding and should not have denied entry to season ticket holders. It was located on Theodore Street, at Waller Street, at the present location of the Arts Hall of the University of Ottawa, near the Rideau Canal.
