1250 René-Lévesque, also known as the IBM-Marathon Tower, is a 226 m (741 ft), 47-story skyscraper in Montreal, Quebec, Canada. The building was designed by Kohn Pedersen Fox Associates for IBM Canada and Marathon Realty, hence the former name "IBM-Marathon". It is now named for its address at 1250 René Lévesque Boulevard West, in the Ville-Marie borough of Downtown Montreal. It is adjacent to the Bell Centre and Windsor Station to the south, and stands on the site of the former American Presbyterian Church.
