The Jewish Encyclopedia is an English encyclopedia containing over 15,000 articles on the history, culture, and state of Judaism and the Jews up to the early 20th century. It was originally published in 12 volumes by Funk and Wagnalls of New York City between 1901 and 1906 and reprinted in the 1960s by KTAV Publishing House. The work's scholarship is still highly regarded: the American Jewish Archives has called it "the most monumental Jewish scientific work of modern times" and Rabbi Joshua L. Segal noted that, "For events prior to 1900, it is considered to offer a level of scholarship superior to either of the more recent Jewish Encyclopedias written in English." It is now in the public domain and hosted at various sites around the internet. 

The encyclopedia's managing editor was Isidore Singer. The editorial board was chaired by Isaac K. Funk and Frank H. Vizetelly. The other editors participating in all twelve volumes were Cyrus Adler, Gotthard Deutsch, Richard Gottheil, Joseph Jacobs, Kaufmann Kohler, Herman Rosenthal, and Crawford Howell Toy. Morris Jastrow, Jr. and Frederick de Sola Mendes assisted with volumes I & II; Marcus Jastrow with volumes I, II, & III; Louis Ginzberg with the first four volumes; Solomon Schechter with volumes IV through VII; Emil G. Hirsch with volumes IV through XII; and Wilhelm Bacher with volumes VIII through XII. William Popper served as the assistant revision editor and chief of translation for Vols. IV through XII.
