Nashoba's Key (March 26, 2003 – May 28, 2008) was a bay filly thoroughbred race horse by (Roberto) out of Nashoba (Caerleon) who went undefeated in her first seven starts in the Southern California racing circuit, before placing 4th in the 2007 Breeders' Cup Filly & Mare Turf. The 4-year-old returned to the turf for the GI Yellow Ribbon Stakes at Santa Anita Park's Oak Tree meet on Sept 29 for a win against the slimly favored Citronnade. Nashoba's Key stalked the pace-setting Citronnade until the top of the stretch, where the pair dueled and Nashoba's Key pulled ahead by 3/4 of a length.
