Elmstein is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Bad Dürkheim district in Rhineland-Palatinate, Germany.
Elmstein lies in the Palatinate Forest. The municipality belongs to the Verbandsgemeinde of Lambrecht, whose seat is in the like-named town.
Elmstein's Ortsteile are, besides the namesake one, Appenthal, Erlenbach, Harzofen, Helmbach, Iggelbach, Mückenwiese, Röderthal, Schafhof, Schwabenbach, Schwarzbach, Stilles Tal, Speyerbrunn and Wolfsgrube.

Elmstein arose from the Castle Elmstein, which itself was built in the 12th century by the Counts Palatine of the Rhine. The outlying centres arose later, mostly as extension settlements for lumberjacks, as a location of a sawmill or, like Röderthal, as a mining settlement.
On 1 January 1976, a centre with 207 inhabitants was transferred from the municipality of Wilgartswiesen to Elmstein.
In 2007, 51.5% of the inhabitants were Evangelical and 30.3% were Catholic. One peculiarity is the Free Religious Community founded in 1921, which with a roughly 5% share of the population stands as the Palatinate’s second biggest Free Religious Community. The rest practised other faiths or none.
The council is made up of 20 council members, who were elected at the municipal election held on 7 June 2009, and the honorary mayor as chairman.
The municipal election held on 7 June 2009 yielded the following results:
The German blazon reads: In Silber zwei gekreuzte rote Doppelhaken, bewinkelt von vier sechsstrahligen goldenen Sternen.
The municipality's arms might in English heraldic language be described thus: Argent two cramps per cross gules, the one per fess surmounting the one per pale, between four mullets Or.
