Riley Reiff (born December 1, 1988) is an American football offensive tackle for the Chicago Bears of the National Football League (NFL). He played college football at Iowa and was drafted by the Detroit Lions in the first round, 23rd overall of the 2012 NFL Draft. He previously played for the Lions from 2012 to 2016 and the Minnesota Vikings from 2017 to 2020.
Born in Parkston, South Dakota to Jo and Tom Reiff, Riley attended Parkston High School, where he was a two-time South Dakota Elite 45 team selection under head coach Jon Mitchel. Reiff was a two-way player for the Trojans, receiving first-team All-State honors at defensive end as a sophomore and junior, as well as first-team All-State honors at tight end as a senior. As a senior in 2007–08, Reiff was named South Dakota Gatorade Player of the Year. During his high school career, Reiff recorded 261 total tackles, 23 sacks and eight interceptions on defense, and also caught 27 passes for 321 yards and nine touchdowns on offense.
In addition to football, Reiff also lettered in golf, track and was a three-time wrestling champion with a career record of 121–1, claiming three state titles. Reiff also excelled in the throwing events for the Parkston track and field team, owning personal-bests throws of 54'5" (16.59 m) in the shot put and 147'8" (45.01 m) in the discus throw.
Reiff was listed as a three-star defensive end prospect by Rivals.com and was ranked 28th nationally among senior strongside defensive ends. When it came to recruiting, one of Reiff's most persistent suitors was Iowa assistant coach Reese Morgan, who also lured former Vikings' linebacker Chad Greenway to Iowa City back in 2001. Reiff initially committed to the Hawkeyes in April 2007, while still a junior at Parkston. He later had second thoughts and switched his verbal commitment to Nebraska, indicating that he "pulled the trigger a little too early" with Iowa, but when the Cornhuskers started sinking under the direction of Bill Callahan, Reiff found his way back to the Hawkeyes.
After redshirting his initial year at Iowa, Reiff started 11 of 13 games on the Hawkeyes' offensive line—three at left tackle, seven at left guard and final game at right tackle. He was named third team Freshman All-America by College Football News. In his sophomore year, Reiff replaced Bryan Bulaga at left tackle, starting all 13 games of the season. He was named second team All-Big Ten by league coaches and media.
A preseason All-American, Reiff started all 13 games at left tackle in his junior season as well. He was named All-Big Ten by coaches and media, as well as All-American by Pro Football Weekly, which evaluates players on NFL prospects and draft value rather just college production. On January 4, 2012, only a few days after Iowa's loss in the 2011 Insight Bowl, Reiff announced his decision to forgo his final year of eligibility at Iowa, entering the 2012 NFL Draft.
Already prior to his junior season, Reiff has been projected as a potential first round NFL Draft. In October 2011, Sports Illustrated′s Tony Pauline ranked him as the No. 14 prospect on his midseason draft board. Prior to the NFL Combine in February 2012, Reiff was still perceived as a top-15 pick. At the combine, Reiff displayed decent athleticism but disappointed with his measureables; his 33+1⁄4 in (84.5 cm) arms—although longer than those of Joe Thomas (32+1⁄2 in or 82.6 cm) and Jake Long (32+7⁄8 in or 83.5 cm)—were deemed too short for an NFL left tackle. As a result, Reiff dropped out of the first round in some post-combine mock drafts. However, Mike Mayock still ranked him the No. 2 offensive tackle, behind Matt Kalil, after the combine, just as he did prior to the combine.

Reiff was drafted by the Detroit Lions at 23rd overall in the 2012 NFL Draft. He was the second of only two offensive tackles selected in the first round of the 2012 NFL Draft (behind Matt Kalil, who was selected 4th overall by the Vikings). Reiff's duties in his rookie campaign were limited to that of a blocking tight end/H-back. He earned his first career start in Week 4 against the Minnesota Vikings on September 30. Reiff had one start at the left tackle position coming in the teams Thanksgiving Day matchup against the Houston Texans. In Week 14, he rotated in the offensive line as usual and also returned a short kickoff for 10 yards.

He prepared for his expanded duties by adding over 12 pounds of muscle. He started at left tackle in the season opener game against Minnesota on September 8 and helped the Lions gain 481 yards of total offense. Reiff ended up starting all 16 games at left tackle and helped pave the way for 15 rushing touchdowns and an average of 392.1 net yards per game, the sixth-best mark in the league. Regarding to pass blocking, the Lions ranked second in the NFL in sacks allowed with 23.
In 2014, Reiff started his mainstay at left tackle in Week 1 against the New York Giants on September 8 and provided protection that led to 20 first downs for the Lions offense. He missed the first game of his NFL career due to injury on Thanksgiving Day, but rebounded to start all 15 games he played in.
