In enzymology, a cinnamate beta-D-glucosyltransferase (EC 2.4.1.177) is an enzyme that catalyzes the chemical reaction

UDP-glucose + trans-cinnamate ${\displaystyle \rightleftharpoons }$ UDP + trans-cinnamoyl beta-D-glucoside

Thus, the two substrates of this enzyme are UDP-glucose and trans-cinnamate, whereas its two products are UDP and trans-cinnamoyl beta-D-glucoside.

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-glucose:trans-cinnamate beta-D-glucosyltransferase. Other names in common use include uridine diphosphoglucose-cinnamate glucosyltransferase, and UDPG:t-cinnamate glucosyltransferase.
