Frederick Warren Cozens was an American college basketball, football, and boxing coach. He was the first head coach of both basketball and football at UCLA and served as the school's athletic director from 1919 to 1942. Cozens was born in Portland, Oregon in 1890. His father, Frederick Cozens, was emigrated from England in 1870 and became a salesman at a hardware store in Portland. His mother Carrie E. Cozens was born in Indiana in 1858. Cozens had an older sister, Ella M. Cozens, born in 1884. He received bachelor's and master's degrees from the University of California in 1915 and 1918, respectively, and a Ph.D. at the University of Oregon in 1928. Cozens was employed by the University of California for nearly 40 years. He began as a teaching fellow and physical education instructor at Berkeley from 1915 to 1919. In June 1917, he was employed as an instructor of physical education at the University of California at Berkeley, California. In 1919, Cozens moved to the Southern Branch of the University of California, now known as UCLA, where he served as the Director of Physical Education and Athletics and professor of physical education from 1919 to 1942.

Cozens remained the Southern Branch's basketball coach through 1921 and guided them to a 20-4 record. His Southern Branch football teams compiled a 2-6 record. The Southern Branch did not participate in an athletic conference until 1920, so the 1919 football team played a schedule full of localhigh schools and other assorted teams. Cozens also served as the dean of UCLA's college of Applied Arts from 1939 to 1942. At the time of the 1920 United States Census, Cozens was living in Los Angeles with his wife Helen J.
