Holt Renfrew Ogilvy, formerly and still colloquially Ogilvy, is a Canadian department store located on Saint Catherine Street West in the downtown core of Montreal, Quebec, Canada. It has been owned by the Selfridges Group, which itself is owned by British-Canadian businessman Galen Weston, since 2011. Through this ownership, it is affiliated with the Canadian department store Holt Renfrew and the European department stores Arnotts, Brown Thomas, de Bijenkorf, and Selfridges. The store is the only one of four major west-end retailers in Montreal that still operates with its original name, and is nicknamed the "grande dame of Saint Catherine Street".

Sainte-Catherine Street is the primary commercial artery of Downtown Montreal, Quebec, Canada. It crosses the central business district from west to east, beginning at the corner of Claremont Avenue and de Maisonneuve Boulevard in Westmount, and ending at the Grace Dart Extended Care Centre by Assomption metro station, where it folds back into Notre-Dame Street. It also traverses Ville-Marie, passing just east of Viau in Mercier–Hochelaga-Maisonneuve. The street is 11.2 km long, and considered the backbone of Downtown Montreal.
