Blue Norther (1961–1972) was an American Thoroughbred racehorse who, along with Tosmah and Miss Cavandish, was a top filly in United States racing in 1964. Ridden by jockey Bill Shoemaker and trained by Wally Dunn, she won all five of her 1964 starts including three major races for fillies of her age group.
Retired to broodmare duty after being diagnosed with a chipped sesamoid bone, Blue Norther was bred twice to Bold Ruler and once to Buckpasser but none of the foals went on to successful racing.
Blue Norther died of a twisted intestine at Claiborne Farm on June 9, 1972.
