Judeo-Latin (also Judæo-Latin), La‘az, or Ebraico-Latino is a presumed Jewish language for many scattered Jewish communities of the former Roman Empire, but especially by the Jewish communities of the Italian Peninsula and Transalpine Gaul.
It is believed that Judæo-Latin is the predecessor of all the Judæo-Romance languages.
There is not much extant record for the Judæo-Latin language. Leo Levi found some hebraisms in a few epigraphs in Italy.
Other possible source for Judæo-Latin are loanwords in other languages, like in Sardinian cenabura [ken'abura] 'Friday' (from Latin cena pura) and caputanni, 'September', a literal translation of Rosh Ha-Shanah.
The historical relationships between the various Judeo-Romance languages are subject to debate, and are only tenuously demonstrable at best. These languages include:

- WEINREICH, Max (1956). The Jewish languages of Romance stock and their relation to earliest Yiddish. RPh 9: 403-428.
