The James Simon Gallery (James-Simon-Galerie) is the central entrance building and visitor center of the famous Museumsinsel (Museum Island) in Berlin.

Opened in 2019 and designed by British architect David Chipperfield, the James Simon Gallery is not a museum in itself, but rather an elegant and modern service building that functions as the "living room" of Museum Island. The name honors James Simon, one of Berlin's greatest art patrons.

The gallery offers:

- A centralized information and ticketing center.

- A large museum shop.

- A café and restaurant.

- Auditorium and temporary exhibition rooms.

- Direct underground access to four of the island's five museums (Altes Museum, Neues Museum, Bode-Museum and, when it reopens, the Pergamon Museum).
