John Churchill Chase (dates?) was a cartoonist and writer. He was known for his editorial cartoons and his works on the history of his native New Orleans and Louisiana.

He is the author of the book, Frenchmen, Desire, Good Children and Other Streets of New Orleans. This book went through several popular editions from the 1960s through 1997, and has gone on to be widely acclaimed as a great chronicling of the history of New Orleans through the naming of its streets.

Chase's other works include the book Louisiana Purchase: an American Story.

He was long a cartoonist for the newspaper The States-Item, in addition to doing editorial cartoons on television on WDSU during the 1960s. He did a mural depicting the history of New Orleans in cartoons for the main branch of the New Orleans Public Library.

Chase taught New Orleans history at Tulane University and cartooning at the University of New Orleans.

A small street in the New Orleans Central Business District was named "John Churchill Chase" after his death. This was a section of street formerlly named Calliope (one of a series of streets in the area named after the Muses). This street runs perpendicular to the Mississippi River, through the New Orleans Warehouse District, about two blocks downriver (east) from the Crescent City Connection Bridge.
