Ruth Bush is a former My Little Pony artist and sculptor. Bush was educated at Kutztown University, obtaining a Bachelor of Fine Arts in Advertising Art, and later was hired by Hasbro Toys to produce various art-pieces for early My Little Pony toys and merchandise. She is in particular notable for being one of the very few identified artists of the Generation 1 era.
From 2006 to 2013, Bush owned an art gallery in Jim Thorpe, Pennsylvania. In 2016, her interest in My Little Pony was "revived" and she began interacting with the fandom of the series, appearing at the 2016 My Little Pony Fair and was interviewed at My Little Pony Talk.
