The Brooklyn Royal Giants were a professional Negro league baseball team based in Brooklyn, New York. Formed in 1905 by John Wilson Connor (1875–1926), owner of the Brooklyn Royal Cafe, the team initially played against white semi-pro teams. They were one of the prominent independent teams prior to World War I before organized league play began.
In 1907, the Brooklyn Royal Giants joined the National Association of Colored Baseball Clubs of the United States and Cuba. The league lasted three seasons and included the teams Philadelphia Giants, Cuban X-Giants, Cuban Stars of Havana, and the Cuban Giants of New York.
During the 1920s, under the ownership of Nat Strong, a white New York City booking agent, the team fell into somewhat of a decline, and did very poorly while in the Eastern Colored League. The Giants played their home games while part of the Eastern Colored League at Dexter Park in Queens.
