Ban Kuti Jihn Museum, also transliterated Baan Kudichin Museum and known in Thai as Phiphithaphan Ban Kuti Jihn, is a small family-run museum that is housed in a building that used to be the home of a Catholic family in the Kuti Jihn Community (fig.).

The museum is dedicated to the history, culture and traditions of this old Portuguese - Thai community, especially the historical events in the period immediately after the fall of Ayutthaya in 1767.

These events include the battle led by General Taksin that drove the Burmese out of Siam, with the support from the Portuguese in terms of weapons supply, such as of cannons and muskets, but also Portuguese mercenaries.
