Sea o'Erin Stakes

The Sea o'Erin Stakes was American Thoroughbred horse race held annually in early September at Arlington Park racetrack in Arlington Heights, Illinois. A Grade III event open to horses age three and older, it was contested on turf over a distance of one mile (8 furlongs).

Inaugurated in 1980 as the Sea o'Erin Handicap, the race was run at various distances:
 * $1 1/8$ miles : 1980, 1987
 * $1 1/16$ miles : 1981–1985

Due to heavy rains, the 1996 race was switched from the turf course to the main dirt track.

There was no race run in 1986, 1988, 1995, and 1997–2000.
