Doriemus (17 November 1990 – 11 January 2015) was a Thoroughbred racehorse who began his career in New Zealand and rose to prominence in Australia by winning the Caulfield and Melbourne Cups in 1995.

[2][3][4] After two wins from three starts in New Zealand, Doriemus was transferred to Lee Freedman late in his three-year-old term, in the winter of 1994.

Doriemus's jockey, Greg Hall, believed he had won the 1997 Melbourne Cup, and gave a wave of his whip after crossing the line, but the photo showed Might and Power had prevailed by the barest of margins.

In the autumn, Doriemus was again placed behind Might and Power in the Mercedes Classic, and was runner-up to Tie the Knot in the Sydney Cup.

Doriemus was retired to Living Legends, the International Home of Rest for Champion Horses in Woodlands Historic Park, Greenvale, Victoria.
