family of American circus proprietors who created the Ringling Brothers circus empire in the late 19th century.

The sons of August Rüngeling, a German-born harness maker, Charles, Albert, Otto, Alfred, and John in 1882 formed a song-and-dance troupe, the Classic and Comic Concert Co., and went on the road with it for two seasons. They began adding circus acts to their show, and they organized their first small circus, which opened on May 19, 1884, in their hometown of Baraboo, Wis.; from there they toured the U.S. Midwest. Their progress was slow until they acquired their first elephant in 1888, after which the circus expanded rapidly. Charles was the guiding managerial force behind the circus for many years. In 1890 the Ringling Brothers first began loading their circus wagons on railway cars, enabling them to make a much longer tour. By 1900 the Ringling Brothers were actively competing with the Barnum & Bailey Circus, and they subsequently started buying up other circuses. They acquired the Forepaugh-Sells Circus in 1906, and, after Bailey's death in 1906, they bought the Barnum & Bailey Circus in 1907, thus becoming the leading circus in the country.
