Sol Felty Light (May 5, 1886 – June 21, 1947) was an American zoologist, entomologist, and professor at the University of California, Berkeley, known for his research on tropical marine invertebrates and caste development in termites. From 1913 to 1947, he published approximately 70 papers, mainly on the subject of entomology. In the 1920s, he began teaching invertebrate zoology, expanding class field trips in the 1930s with five-week summer sessions at Moss Beach and Dillon Beach.

His class syllabus on zoology was originally designed for students at Berkeley, but were later published as an invertebrate zoology textbook and field guide, becoming the first compendium of marine invertebrates in the north central California coastal region for specialists working in the area between Hopkins Marine Station and Bodega Marine Laboratory. After Light's death, the book was edited, revised, and expanded by Ralph I. Smith and other contributors, becoming known as Light's Manual. After Smith himself died, the book was renamed the Light and Smith Manual in his honor.
