The Aichi Hai (Japanese 愛知杯) is a Grade 3 horse race for Thoroughbred fillies and mares aged four and over, run in March over a distance of 1,400 meters on turf at Chukyo Racecourse.

[1] The Aichi Hai was first run in 1963 at 2,000 meters and has held Grade 3 status since 1984.

The Aichi Hai was run in December until 2014 and was open to three-year-olds before being changed to January: the change meant that the race was not run in 2015.

The race was open to both male and female horses up to 2003.
