Phi Beta Delta (ΦΒΔ) was an American college social fraternity for Jewish students.

Phi Beta Delta was founded at Columbia University on April 12, 1912 as a college social fraternity for Jewish students.

Its eight founders were David H. Cohen, Henry C. Fenton, William Haas, Darcy M. Heinemann, Joseph Michtom, Samuel Null, Julius Rudd, and Bernard Shapiro [1][2] The founders stated, "Its purpose is to inculcate among its membership a fine spirit of loyalty, activity, and scholarship toward their Alma Mater, to develop the highest ideals of conduct, and to promote a close fraternal bond through means of carefully selected associates.

In 1934, Phi Beta Delta absorbed the UPenn chapter of Omicron Alpha Tau, a smaller Jewish fraternity that was dispersing that year.

[4] The fraternity had alumni clubs in Boston, Chicago, Denver, Los Angeles, New Jersey, New York City, Oklahoma, Philadelphia, St. Louis, and Western Pennsylvania.
