John J. Wildberg (September 4, 1902 – February 8, 1959) was an American copyright attorney, who later became a theatre producer.
Together with Cheryl Crawford, he co-produced the first revival of Porgy and Bess (1942) and One Touch of Venus (1943).
Wildberg's fourth marriage (her third), to novelist Ursula Parrott in 1934, ended in June 1938 on the grounds of his intolerable cruelty.
Wildberg had various business ventures in London, England, and eventually moved there in 1951.
He died there on February 8, 1959, and was cremated in Golders Green Crematorium.
