San Giorgio dei Greci is a church in the sestiere (neighborhood) of Castello, Venice, northern Italy. It was the center of the Scuola dei Greci, the Confraternity of the Greeks in Venice. Around this period there was a similar church in Naples called Santi Pietro e Paolo dei Greci. There was also a Greek Brotherhood of Naples.

The Scuola dei Greci was the confraternity of the Greek community in Venice. Its members were primarily Greeks, but also included Serbs.
