Heir Hunters is a BBC television programme focusing on attempts to find missing or unknown heirs, entitled to deceased people's estates before the British Treasury lawfully collects the money.

It was announced in 2011 that Heir Hunters would run in both BBC One daytime and in primetime television on BBC Two that autumn. The sixth series began at 9:15am on BBC One on 16 April 2012, it is expected BBC Two versions of these shows will air at a later date.
