Scott Thomas Linehan (born September 17, 1963) is an American football coach who serves as a senior offensive assistant for the New Orleans Saints of the National Football League (NFL). He recently was an offensive analyst at Montana. He was the passing game coordinator for LSU in 2020. He was previously the head coach of the St. Louis Rams and the offensive coordinator for the Dallas Cowboys, Miami Dolphins, Minnesota Vikings and Detroit Lions. Prior to becoming an NFL coach in 2002, Linehan was a college assistant coach for 13 seasons.

Linehan was born and raised in Sunnyside, Washington, about three hours southeast of Seattle, in the lower Yakima Valley of eastern Washington. He was a three-year starter at quarterback at Sunnyside High School, where his father was principal. Linehan graduated from high school in 1982 and accepted a scholarship to play college football at the University of Idaho in Moscow, about two hundred miles (320 km) to the east. He was a member of Dennis Erickson's first recruiting class as a collegiate head coach. Linehan's brothers, Ron and Rick, had played at Idaho in the 1970s, and were team leaders on defense.

Linehan was a quarterback for the Vandals under head coaches Erickson (1982–85) and Keith Gilbertson. He backed-up junior All-American Ken Hobart as a true freshman in 1982, then redshirted in 1983. Linehan became the starter in 1984 as a redshirt sophomore, but broke his clavicle early in the second game and missed most of that game and two additional starts. Following two successful seasons behind Hobart, the Vandals struggled to a 2–5 record in 1984, then won four straight to finish 6–5 and third in the Big Sky. It concluded with a 37–0 shutout at Bronco Stadium for a third consecutive win over rival Boise State, a streak that extended to twelve straight in 1993.

Linehan led the Vandals to a 5–1 record as a starter in 1985, then a stress fracture in his right foot required surgery and sidelined him for the season. Idaho won the Big Sky title and had consecutive Division I-AA playoff appearances in 1985 and 1986. Finally healthy for a full season as a fifth-year senior in 1986, Idaho went 8–3 in the regular season and he threw for 2,954 yards, ending his college career with over 7,000 yards.

Tom Cable and Mark Schlereth both blocked for Linehan during his college career at Idaho. Linehan credits Erickson as the "biggest influence" on his attack-style offensive philosophies.

Not selected in the 1987 NFL draft, Linehan signed as an undrafted free agent with the Dallas Cowboys on May 6, 1987. A shoulder injury quickly ended his playing career, when he was cut at the start of his rookie training camp.

Linehan began his coaching career as a volunteer coach at Sunset High School in Portland in 1987. At this time, he also was helping a friend with his business, selling class rings for Jostens.

Linehan's college coaching career began in 1989 at his alma mater, the University of Idaho, as wide receivers coach under first-year head coach John L. Smith. After two seasons at Idaho, Linehan coached a year at UNLV, and returned for two more seasons at Idaho as offensive coordinator. Linehan then spent five years at Washington in Seattle under Jim Lambright and three at Louisville under John L. Smith.
