Ban Mi (, ) is a district (amphoe) in the western part of Lopburi province, central Thailand.
The district was created in 1883, then named Sanam Chaeng. When the district office was moved to Ban Huai Kaeo, the district name was changed to Huai Kaeo as well. When in 1898 the Thai government built the Northern Railway through the district, the district center was moved to Ban Sao (Thai à ¸Âà ¹Âà ¸²à ¸Âà ¹Âà ¸Âà ¹Âà ¸²) and the district name was changed back to Sanam Chaeng. In 1917 it was renamed Ban Sao as the name of the tambon of the district center. Finally the Thai government changed the name to Ban Mi in 1939.
The name Ban Mi is the name of an old town of Phuan people who migrated from Laos to Siam around 1870. The name originates from a hand weaving method to weave cotton or silk fabric, named Mat Mi (à ¸¡à ¸±à ¸Âà ¸«à ¸¡à ¸µà ¹Â) in Thai.
