On which famous Parisian avenue is Louis Vuitton's flagship store located?

Louis Vuitton’s flagship store is located on the Champs-Élysées.

The Paris flagship occupies a prominent address at 101 Avenue des Champs-Élysées, one of the city’s best-known shopping avenues. The location places the house among major fashion, jewelry and lifestyle brands near the Arc de Triomphe, making it both a retail destination and a landmark associated with luxury shopping in Paris.

Louis Vuitton has maintained a presence on the avenue for decades. The building was extensively redesigned, and the store reopened in 2005 with architecture by Eric Carlson. Its expanded presentation brought together handbags, luggage, ready-to-wear, accessories and other collections in a large, highly theatrical setting.

Avenue Montaigne and Rue du Faubourg Saint-Honoré are also strongly associated with Parisian luxury fashion, so they are plausible distractors. However, the Louis Vuitton flagship referenced by this question is specifically the Maison on the Champs-Élysées. The avenue’s name is conventionally written with the accent in “Élysées.”
