In 1155, Hettenleidelheim had its first documentary mention and was originally made up of two centres: Hitenheim (later Hettenheim) and Luttelheim (later Leidelheim).

In the time of the Reformation, Hettenheim and Leidelheim, along with the outlying Protestant parishes of Eisenberg and Wattenheim, became Lutheran.

The Jewish community that once existed in the municipality (synagogue in Wattenheim) is still witnessed by two old hidden graveyards that were used from the 18th to the 20th century, and where there are some gravestones worth seeing.

The municipal election held on 7 June 2009 yielded the following results:[5] Since 2016, the Mayor of Hettenleidelheim has been Steffen Blaga (CDU).

The German blazon reads: In Schwarz ein schrägrechtsgestellter silberner Schlüssel mit abwärtsgekehrtem Bart, unten rechts begleitet von einem schwebenden goldenen Andreaskreuz.

The arms were approved by the now abolished Regierungsbezirk government in Neustadt in 1979 and go back to a seal from 1758.

The key symbolizes the High Foundation of Worms whose patron was Saint Peter.

The lands once served as the churchyard for Hettenheim's mediaeval Saint Stephen's Chapel (Stephanus-Kapelle), which between 1720 and 1724 was forsaken in favour of the then newly built parish church in Leidelheim.
