Mandelate racemase ({{EnzExplorer|5.1.2.2}}) is a bacterial enzyme which catalyzes the interconversion of the enantiomers of mandelate via an enol intermediate.{{cite journal | vauthors = Gunsalus CF, Stanier RY, Gunsalus IC | title = The enzymatic conversion of mandelic acid to benzoic acid.

: (S)-mandelate $\backslash rightleftharpoons$ (R)-mandelate

It is a member of the enolase superfamily of enzymes, along with muconate lactonizing enzyme and enolase.
