James C. Crumlish Jr. (May 5, 1920 – March 17, 1992) was an American attorney and politician. He served as the District Attorney of Philadelphia, Pennsylvania between 1962 and 1966, and as a judge of the Commonwealth Court of Pennsylvania from 1970 until his death. Early life He was born and raised in Philadelphia. His father, James Sr., was a judge of the Pennsylvania Court of Common Pleas and was a recognized figure within the city's Democratic Party hierarchy. Crumlish attended Georgetown University, and was in the process of earning his J.D. from the University of Pennsylvania School of Law when World War II broke out. He joined the Navy, and served as a senior line officer aboard the battleship . He took part in eight major battles and achieved the rank of lieutenant commander when he was 25 years old.

He specialized in litigation while practicing general law, and in 1952, was appointed to the Philadelphia Registration Commission.
