The Ottawa Capitals were the competing clubs of the Capital Amateur Athletic Association (CAAA) of Ottawa, Ontario, Canada. The Association competed in ice hockey, lacrosse and other athletics.
The Capital Lacrosse Club was also successful, and won the first Minto Cup in 1901. The Capitals lacrosse club was one of the first amateur organizations that gave some of its players small amounts of money, causing a scandal that led to several of their athletes, notably Rat Westwick being banned from amateur play against other organizations that frowned on any dilution of the amateur standard.
