Ban Dan Lan Hoi (Thai: บ้านด่านลานหอย, pronounced [bâːn dàːn lāːn hɔ̌j]) is a district (amphoe) in the western part of Sukhothai province, in the lower north of Thailand.

[1][2] In the Sukhothai era, the district area was the western camp of patrolling soldiers.

The pronunciation changed with time to the present-day Ban Lan Hoi.

In the Rattanakosin era, the Interior Ministry created a new sub-district (tambon) named Ban Dan.

When the Charot Withi Thong road, connecting Sukhothai with Tak was finished, they moved the office to Tambon Ban Dan again.
