The Former British Consulate of Hakodate (Japanese: 函館市旧イギリス領事館, Hepburn: Hakodate-shi kyū Igirisu ryōjikan), also officially known as the Opening-Port Memorial Hall and commonly called the Old British Consulate, is a historic house museum meant to preserve the now-defunct consulate of the United Kingdom to Hakodate, Japan, and memorialise the opening of Hokkaido to foreign trade.

Hakodate was one of the first Japanese ports to open up to foreign trade after the Perry Expedition alongside Yokohama and Nagasaki in 1859.

It was moved from its original location to a plot next to the Orthodox church at the Russian consulate four years later.

[5] In 1979, the city of Hakodate gave the building the designation of "tangible culture property", later converting it into its current status as a "memorial hall" in 1992 and opening it to the public after being restored two years later.

[1][4][6] It is currently host to exhibits on the opening of Hakodate on the first floor, a recreation of the consul's office and living room, alongside other displays, on the second floor, and a tea room named "Victoria Rose".
