Yamada Nagamasa (山田 長政, 1590–1630) was a Japanese adventurer who gained considerable influence in the Ayutthaya Kingdom at the beginning of the 17th century and became the governor of Nakhon Si Thammarat province, which is on the Malay Peninsula in present-day Southern Thailand.

From 1617 until his death in 1630, Yamada Nagamasa was head of the Thai village referred to as Ban Yipun ('Japanese village') in the Thai language. This village was within the city of Ayutthaya (the capital city of the Ayutthaya Kingdom). Ban Yipun was home to roughly 1,000 Japanese citizens and was headed by a Japanese chief who was nominated by Ayutthayan authorities. Its inhabitants were a combination of traders, Christian converts who had fled their home country following the persecutions of Toyotomi Hideyoshi and Tokugawa Ieyasu and Rōnin (unemployed former samurai) who had been on the losing side at the Battle of Sekigahara (1600) or the Siege of Osaka (1614–15). The Christian community seems to have been in the hundreds, as described by Padre António Francisco Cardim, who recounted having administered sacraments to around 400 Japanese Christians in 1627 in the city of Ayutthaya.^[1]
