Berlo (foaled April 10, 1957 in Virginia) was an American Thoroughbred Champion racehorse.

Berlo was a brown mare bred by William duPont, Jr. at his Walnut Hall Farm near Boyce, Virginia. She was out of the mare Faberose, a daughter of duPont's Santa Anita Handicap winner, Rosemont. Her sire was the good British runner Heliopolis, a son of the six-time Leading sire in Great Britain and Ireland, Hyperion. Berlo was trained by Richard Handlen,

In 1960 Berlo won five major races including the Coaching Club American Oaks,^[1] the Beldame Handicap,^[2] and on October 12, the grueling mile and a half Ladies Handicap.^[3] at New York's Belmont Park. However, the next day her handlers announced she would not race again that year.^[4] Berlo's dominating performances earned her 1960 American Champion Three-Year-Old Filly honors.^[5]

Berlo did not return to racing for nearly nine months.^[6] Unable to be competitive, she did not win a major race in 1961.

As a broodmare, Berlo met with little success, only Odd Dancer, a son by Native Dancer, was a minor race winner.
