D. Elden Beck (1906-1967) was a professor of zoology and entomology in Utah.

D. Elden Beck was born on April 11, 1906, in Spanish Fork, Utah to Mitchell Robertson Beck and Ruth Eleanor Davis. He was raised in The Church of Jesus Christ of Latter-day Saints, and was baptized in 1914. That same year he moved with his family to McGill, Nevada, and then in 1921 relocated again to Lava Hot Springs, Idaho. Beck graduated from Lava Hot Springs High School in 1925, then attended Brigham Young University in Provo, Utah. There he studied zoology and entomology, earning his bachelor's degree in 1929 and a master's degree in 1930. He then continued his education at Iowa State College, where he received his Ph.D. in 1933. In May of that year he married Florence Robinson in the Salt Lake Temple; they had four children.

After graduating from Iowa State, Beck was appointed as head of the Biology Department at Dixie State College in St. George, Utah. He taught there until 1938 when he joined the faculty of the Zoology and Entomology Department at Brigham Young University. During the Second World War, Beck left the university to serve in the Medical Entomological Service in the United States Army Medical Department. He served from 1943 to 1945 at bases in the United States and in Guadalcanal. Afterward he rejoined the university faculty, continuing his research on malaria-carrying insects in Taiwan and helping to set up a mosquito abatement program in Utah County. Later in his career he also became involved in studying the effects of atom bombs on the native wildlife in Nevada.

Beck served as chair of the Department of Zoology and Entomology at Brigham Young University between 1962 and 1965. He died in Provo, Utah on August 9, 1967.
