Hystericalady (foaled April 2, 2003), is a multiple stakes winning American Thoroughbred race horse.

Hollendorfer trained the filly at Golden Gate Fields Like Funny Cide, Hystericalady is a bright chestnut.

In September 2008, running on a synthetic surface (on which her record stands at 0-for-5), she struggled the entire length of the stretch with the speed horse, Santa Teresita, as well as with the track and still finished second.

On October 24, 2008, in her second Breeders' Cup Ladies' Classic, Hystericalady was in a dead heat[1] with Carriage Trail for fourth place[2] against a strong field of eight Grade I winners: Zenyatta (race day favorite at 1-2 choice), Cocoa Beach, Music Note, and Ginger Punch.

Hystericalady was purchased for $3 million by Sheikh Mohammed during the 2008 Keeneland November breeding stock sale Nov. 3 at the Central Kentucky auction house.
