Joseph Reed Ingersoll (June 14, 1786 – February 20, 1868) was an American lawyer and statesman from Philadelphia, Pennsylvania.

He studied law with his father, was admitted to the bar and commenced practice in Philadelphia.

Ingersoll was elected as a Whig to the Twenty-seventh Congress to fill the vacancy caused by the resignation of John Sergeant.

He served about a year, and then retired to private life, devoting himself to literary pursuits.

He was a warm adherent of the Union, and at the time of the American Civil War prepared an essay entitled "Secession, a Folly and a Crime."
