Frank Edward 'Ted' Moss (September 23, 1911 – January 29, 2003) was an American lawyer, judge, and politician who served as a United States Senator from Utah from 1959 to 1977. Born in Holladay, Utah, Moss grew up in a Mormon pioneer family and developed an early interest in public service. He earned a bachelor's degree from the University of Utah in 1933 and a law degree from George Washington University in 1937. Following his legal education, Moss practiced law in Utah and served as an assistant district attorney in Salt Lake County. During World War II, he enlisted in the United States Navy, rising to the rank of lieutenant commander and participating in combat operations in the Pacific Theater.

Moss entered politics after the war, serving as the Salt Lake County attorney from 1947 to 1953 and as a district judge from 1953 to 1956. In 1956, he was elected to the U.S. Senate, defeating incumbent Republican Arthur Vivian Watkins. As a moderate Democrat, Moss focused on consumer protection, environmental issues, and public health. He co-sponsored the Truth in Lending Act of 1968, which required clear disclosure of loan terms to protect consumers from predatory lending practices. Moss also championed the Consumer Product Safety Act and was instrumental in establishing the Occupational Safety and Health Administration (OSHA). His tenure included service on key committees such as Appropriations and Labor and Human Resources.

Moss sought re-election in 1970 and 1976 but lost the latter to Republican Orrin Hatch, ending his Senate career and marking the last time a Democrat held the Utah Senate seat as of 2025. After leaving office, he returned to private law practice in Salt Lake City and remained active in civic affairs until his death. Known for his integrity and bipartisanship, Moss's legacy endures through landmark legislation that advanced consumer rights and workplace safety.
