Stanerra (foaled 4 May 1978) was an Irish Thoroughbred racehorse and broodmare. Unraced at two, she ran twice a three-year-old before showing improved form in 1982 when she won one race and was placed in several good middle-distance races. She reached her peak as a five-year-old in 1983 when she emerged as one of the leading middle-distance performers in Europe.
