Grass Wonder (Japanese グラスワンダー, foaled 18 February 1995) is an American-bred, Japanese-trained Thoroughbred racehorse and sire. In a racing career which lasted from 1997 until 2000 he won nine of his fifteen races including four Grade I races. He was the leading juvenile colt in Japan in 1997 when he was unbeaten in four races, culminating in a victory in the Asahi Hai Sansai Stakes. He missed most of his second season with injury problems but returned in autumn to win the Arima Kinen. He reached his peak as a four-year-old when he won the Takarazuka Kinen and a second Arima Kinen. He failed to win in three races in 2000 and was retired to stud. He has had some success as a breeding stallion.

Grass Wonder is a chestnut horse with a white star, standing 15.3½ hands high bred in Kentucky by Phillips Racing Partnership & John Phillips, of the Darby Dan Farm. He was sired by Silver Hawk, an American-bred colt who finished third in the 1982 Epsom Derby and later became a successful breeding stallion, siring the 1997 Epsom Derby winner Benny the Dip, the 1999 St Leger winner Mutafaweq and the leading American turf performer Hawkster. Grass Wonder's dam Ameriflora was an unraced daughter of Danzig. She was a great-granddaughter of Soaring, an American broodmare who was the ancestor of many major winners including Glorious Song, Saint Ballado, Rahy and Singspiel.
