John Paul Hogan is an American research chemist who along with Robert Banks discovered methods of producing polypropylene and high-density polyethylene.

Hogan was born in Lowes, Kentucky, and earned B.S. degrees in both chemistry and physics at Murray State University of Kentucky in 1942. He taught at both the high school and college level before going to work in research at the Phillips Petroleum Company in 1944. He worked primarily in the area of plastics and catalysts and in 1951 invented crystalline polypropylene and high-density polyethylene (HDPE) with his fellow research chemist Robert Banks. These plastics were initially known by the name "Marlex." Hogan held (jointly) a number of important patents and authored research papers before he left Phillips in 1985 to become a private consultant. Hogan fully retired in 1993.

In 1987, Hogan and Robert Banks together received the Perkin Medal Award and both were given a Heroes of Chemistry award by the American Chemical Society in 1989. In 2001 they were inducted into the National Inventors Hall of Fame.
