This article explains the term Pharisee in Judaism and Christianity; for the drink, see Pharisee (drink).

The Pharisees (Hebrew פְּרוּשִׁים peruschim 'set apart', Latin pharisæ|us, -i, Ancient Greek Φαρισαῖος pharisaios) were a theological, philosophical and political school in ancient Judaism. They existed during the time of the Second Jewish Temple and became the only significant surviving Jewish current after its destruction in 70 CE as a driving force in rabbinic Judaism. In many cases they are also referred to as "scribes". Their spiritual leaders were referred to as Chachamim (to singular Chacham, Hebrew חכמים "sages"). They were not only experts in halakhah (Hebrew הלכה; derived from the verb הלך halach: "to go", "to walk"), the legal part of the tradition of the Jewish faith, but also preachers.

In the New Testament, representatives of the Pharisees are criticized and belittled as hypocrites. In many countries with Christian tradition this predicate has become colloquial for the self-righteous or hypocrite or generally for positions that criticize in a petty way and neglect the context. The background to this polemic is explained in the section "Pharisees and Christianity" below.
