Erlenbach bei Marktheidenfeld (officially Erlenbach b.Marktheidenfeld) is a community in the Main-Spessart district in the Regierungsbezirk of Lower Franconia (Unterfranken) in Bavaria, Germany and a member of the Verwaltungsgemeinschaft (Administrative Community) of Marktheidenfeld.

As part of the Prince-Bishopric (Hochstift) of Würzburg, Erlenbach was in Bavaria's favour secularized in 1803 and passed under the Peace of Pressburg (1805) to Archduke Ferdinand of Tuscany to form the Grand Duchy of Würzburg, whence it passed back to Bavaria in 1814.

Seat apportionment after municipal election in 2008: The community's arms might be described thus: Gules two arrows in saltire the dexters sable and the sinisters Or surmounted by a heart argent, itself surmounted by a bunch of grapes azure, the stalk of the second, the whole between two mullets of six of the third.

The arrows stand for the defence of the village, and the six-pointed stars come from the Wertheim family's roses.

The tinctures come from the arms borne by the Princely Electorate (Hochstift) of Würzburg, to which Erlenbach belonged from 1612 to 1803.
