The commandment to sanctify the progeny of Aaron (Hebrew: מצוות קידוש זרעו של אהרן) is a commandment based in the Hebrew Bible, and developed in rabbinical teaching that requires believers in Judaism to sanctify their priests (kohanim) in various ways. These include assisting him to abstain from any prohibitions in the Law that apply to him, and by affording him first rights in areas relating to holiness and the service of God. In the enumeration of Maimonides this is the 32nd positive commandment of the Law.^[1]

In Hebrew the commandment is literally known as the mitzvah of sanctifying the "seed of Aaron" (Hebrew: מצוות קידוש זרעו של אהרן‎).
