Hansen (foaled April 23, 2009 in Kentucky), nicknamed 'White Lightning' and 'The Great White Hope', is a grey American Thoroughbred racehorse.

He is famous for having a coat that has grayed out to white far more rapidly than is typical, which led sportscaster Frank DeFord to describe him as a "four-legged Steve Martin.

Dominguez flew from Belmont Park to Iowa after a day's riding in New York to guide the colt to his win.

On January 28, 2014, Hansen was represented by his first foal, a chestnut colt out of the mare Havelsee, later named Mookie.

On June 5, 2016, gelding Hansen's Victory (owned by North American Thoroughbred Horse Company, Russell Morrison, and Peter Tom) won a maiden special weight at Hastings Racecourse, becoming his sire's first recognized winner.
