Union Rags (born in March 3, 2009 in Kentucky) is a champion American Thoroughbred racehorse who won the 2012 Belmont Stakes.

In August, he was moved into Grade II company for the Saratoga Special Stakes and won in "impressive"[5] style by more than seven lengths.

On October 8, Union Rags stepped up to Grade I class for the Champagne Stakes at Belmont Park and started the 6/5 favorite against seven opponents.

In the straight, Union Rags made steady progress on the inside to overtake Paynter in the final strides and won by a neck.

"[11] Union Rags was being prepared for a run in the Haskell Invitational when he sustained a tendon injury in his left front leg which ruled him out for the rest of the season.

On April 20, 2016, Union Rags had his first winner in Lady Stardust at Aqueduct in a maiden special weight race going 4+1⁄2 furlongs.
