Ban Pho (, ) is a district (amphoe) in the western part of Chachoengsao province, central Thailand.
The district was established by separating part of Mueang Chachoengsao District in 1903, then named Sanam Chan (à ¸ªà ¸Âà ¸²à ¸¡à ¸Âà ¸±à ¸Âà ¸Âà ¸£à ¹Â) by Prince Marubhongse Siribhadhana, the governor of Monthon Prachinburi. In the past Sanam Chan Subdistrict was on both banks of the Bang Pakong River. Around 1906 the government split the area on the left bank where the district office was located to create Ban Pho Subdistrict.
Later, when King Vajiravudh (Rama VI) built the Sanam Chan Palace in Nakhon Pathom in 1911, as the district name was pronounced the same as the Sanam Chan Palace, the government changed the district name to Khao Din District on 20 July 1914. Later they changed to be Ban Pho district in 1917.
The name Ban Pho refers to 'home of bodhi tree'.
