Stephen Taylor Beuerlein (born March 7, 1965) is an American former professional football player who was a quarterback in the National Football League (NFL). He played college football for the Notre Dame Fighting Irish. After his playing career, he became an NFL and college football analyst for CBS.

In his senior year, Beuerlein led Anaheim's Servite High School to the California Interscholastic Federation 1982 Southern Section Big Five championship, where he was named player of the year. In the first game of the year he played against Ohio's famed Moeller High School. Although Servite led Moeller early in the 4th quarter, Moeller won 29–15, but Beuerlein's performance caught the eye of Notre Dame head coach Gerry Faust, who had coached for 18 years at Moeller prior to taking the Notre Dame job. After Servite went on to win its final eleven games en route to a 31–7 victory over Long Beach Poly in the CIF-SS Big 5 championship game (and a #4 national ranking), Faust offered Beuerlein a full scholarship, and he attended Notre Dame the following year.

As a true freshman in the 1983 Notre Dame season, the 18-year-old Beuerlein got his first start in the fourth game, relieving senior quarterback and four-year starter Blair Kiel, who had begun the season with a 1–2 record. Beuerlein started the remaining eight games of the regular season, splitting playing time with Kiel, and winning his first five starts. He lost his final three starts of the regular season in close games decided by five points or less, but the Irish' 6–5 record was good enough for a Liberty Bowl bid, where Kiel got the start for the first time since the Miami game and led the Irish to a 19–18 victory over Doug Flutie's 13th-ranked Boston College team.

Beuerlein entered his sophomore 1984 season as the starter at quarterback. In the fifth game of the season against #14 Miami, he was knocked out of the game with an injury to his throwing shoulder. He missed only one game, and started the rest of the season's games, taking repeated cortisone injections. He led the Irish to a 4–1 finish to the regular season and a 7–4 record, losing only to #11 South Carolina, and with victories at #6 LSU and #14 USC, before losing in the Aloha Bowl to #10 SMU. In that game, Beuerlein noticed a deterioration in the condition of his throwing shoulder, which had been worsening since the injury. Beuerlein also blamed the injury on throwing a school-record 18 interceptions. After an unsuccessful offseason rehab, Notre Dame sent Beuerlein to a California orthopedist in April, where the doctor discovered a bone chip in his collarbone, which had ground away much of his acromioclavicular joint. He had surgery immediately, which removed an inch of his collarbone and the entire remaining parts of his AC joint.

Five months after surgery to his throwing shoulder, Beuerlein was starting the 1985 season opener at Michigan. Beurlein was benched for the Ole Miss game in favor of sophomore backup Terry Andrysiak after throwing just three touchdowns at that point After good play coming off the bench that game, Beurlein won his starting job back.

Before Beuerlein's senior year, Faust resigned after five seasons. The university then hired Minnesota head coach Lou Holtz. Beuerlein enjoyed his best statistical season in 1986 under Holtz, throwing for 2211 yards, 13 TDs and 7 INTs. In his final collegiate game, Beuerlein threw three second-half touchdowns, helping lead the Irish to an upset over the 17th ranked USC Trojans. The win gave Beuerlein a perfect 4–0 record against the Trojans, the only Notre Dame quarterback ever to do so besides Ralph Guglielmi from 1951 to 1954.

Beuerlein started 39 out of 46 games for the Irish during his four-year career, with a 21–18 record. He graduated in 1987 with a degree in American Studies, having broken nearly every passing and total offense record in Notre Dame history.

Beuerlein was drafted by the Los Angeles Raiders in the fourth round of the 1987 NFL draft, but suffered a season-ending injury in preseason play.
