The Griffintown Horse Palace is a stable in the Griffintown district in Montreal, Quebec, Canada, which dates back to around 1860. For three decades, the stables were run by former Goose Village resident, iceman and calèche driver Leo Leonard, also known locally as Clawhammer Jack. Leonard, who was reported to be the last Irish Quebecer left in Griffintown, retired and moved to Nun's Island in 2011. The sale of his land around his Ottawa Street residence has cast the future of the stables in doubt. Leo and his stables are featured in an episode of Weird Houses. Montreal landscape architect Juliette Patterson has formed a foundation in an attempt to save the Horse Palace, which has also drawn support from the area's historic Irish community.
