Cecil Dale Andrus (born August 25, 1931) is a U.S. Democratic politician from the state of Idaho.

Andrus was born in Hood River, Oregon. He attended Oregon State University from 1948 to 1949 and served in the United States Naval Reserves from 1951 to 1955. He served in the Idaho Senate from 1961 to 1966, and was defeated in a race for Governor in 1966; he again served in the state Senate from 1968 to 1970. He was successfully elected Governor of Idaho in 1970, and reelected in 1974; he resigned the Governorship to serve in President Jimmy Carter's cabinet as Secretary of the Interior from 1977 to 1981. In 1979, when Carter demanded the resignations of his entire cabinet, Andrus refused to comply. He left office in 1981, and again served as governor from 1987 to 1995. He gained national notoriety in 1990 when he vetoed a strict anti-abortion bill. He did not run for reelection in 1994, and left office in January 1995 with a high approval rating.
