The Thought of Skhariya the Jew, much more commonly known in the church terminology as the Heresy of the Judaizers or Zhidovstvuyushchiye, is a religious concept that exists in Novgorod the Great and Grand Duchy of Moscow in the second half of the fifteenth century and markd the beginning of a new era of schism in Russia.

Some scholars consider it to have developed from the earlier Strigolniki religious concept that also had developed in Novgorod in the fourteenth century.

Initially popular among high-ranking statesmen and even the royal court, the concept is persecuted by hegumen Joseph Volotsky and Archbishop Gennady of Novgorod.
