The North East England devolution referendum was an all postal ballot referendum that took place on 4 November 2004 throughout North East England on whether or not to establish an elected assembly for the region.

 Initially, three referendums were planned, but only one took place.
 The votes concerned the question of devolving limited political powers from the UK Parliament to elected regional assemblies in North East England, North West England and Yorkshire and the Humber respectively.
