Kansas City Chiefs
In the 2016 NFL draft, Hill was selected by the Kansas City Chiefs in the fifth round (165th overall). He was the first player from West Alabama to be drafted since 1974, when Ken Hutcherson was selected 97th overall by the Dallas Cowboys. The Chiefs were criticized by fans for the selection due to his past issues with domestic violence and the Chiefs' history with former linebacker Jovan Belcher. General manager John Dorsey had to receive consent from Chiefs' owner Clark Hunt to make the selection and says they thoroughly vetted Hill, which included speaking to the prosecutor that charged him. After drafting him, the Chiefs held a press conference and addressed the issue to the media during the first day of rookie minicamp.
On May 17, 2016, the Chiefs signed Hill to a four-year, $2.58 million contract that included $100,000 guaranteed and a signing bonus of $70,000.
Hill began the 2016 season as the Chiefs' starting punt returner, kick returner, and fourth wide receiver on the depth chart behind veterans Jeremy Maclin, Chris Conley, and Albert Wilson. In the Chiefs' season opener, he made his first NFL catch for a nine-yard touchdown pass from Alex Smith as the Chiefs came back from 3–21 to defeat the San Diego Chargers 33–27 in overtime. During Week 8, Hill caught five passes for a season-high 98 yards and a touchdown during a 30–14 road victory over the Indianapolis Colts. Two weeks later, he had a season-high ten catches for 89 yards, helping the Chiefs come back from 3–17 at halftime to defeat the Carolina Panthers 20–17. In Week 12 against the Denver Broncos, Hill returned a kickoff for an 86-yard touchdown, ran for a three-yard touchdown, and caught a three-yard touchdown pass with less than five seconds left in the fourth quarter, securing the Chiefs a 30–27 overtime road victory. He was the first player with a kick return for a touchdown, rushing touchdown, and receiving touchdown in a single game since Gale Sayers did so for the Chicago Bears in 1965. During his return, he reached a speed of 22.77 miles per hour (36.64 km/h), the fastest speed any NFL player had reached that season. His performance earned him AFC Offensive Player of the Week. In Week 14 against the Oakland Raiders on Thursday Night Football, Hill made a 78-yard punt return for a touchdown, caught six receptions for 66 yards and scored on a 36-yard receiving touchdown, helping the Chiefs win 21–13 and move to first place in the AFC West. He was named AFC Special Teams Player of the Week for his performance. Two weeks later against the Broncos, Hill had a season-high six carries for 95 rushing yards and scored a 70-yard rushing touchdown in the 33–10 victory. In the regular-season finale against the Chargers, he caught five passes for 46 yards, had three carries for 15 yards, and a 95-yard punt return for a touchdown in the 37–27 win. His performance earned him his second AFC Special Teams Player of the Week honor.
Hill finished his rookie season with 61 receptions for 593 yards and six receiving touchdowns, 24 carries for 267 yards and three rushing touchdowns, 14 kick returns for a total of 384 yards and a touchdown, and 39 punt returns for 592 yards and two touchdowns. His punt return yards and yards per punt return average (15.2) ranked first in the league, while his punt return touchdowns (2) tied for first with Andre Roberts and Marcus Sherels. He also appeared in all 16 games with one start, and made seven combined tackles. He was named to the 2017 Pro Bowl as a return specialist. On January 6, 2017, Hill was named first-team All-Pro as a punt returner. He was named to the 2016 PFWA NFL All-Rookie Team on special teams, and was ranked 36th by his fellow players on the NFL Top 100 Players of 2017.
The 2017 season saw Hill focus less on his role as a running back. On September 7, 2017, in the season opening game against the defending Super Bowl champion, the New England Patriots, Hill finished with 133 receiving yards on seven receptions, which included a 75-yard reception for a touchdown, as the Chiefs won 42–27 on the road. In Week 5 against the Houston Texans, he recorded an 82-yard punt return touchdown in the fourth quarter of a 42–34 victory. Three weeks later against the Broncos on Monday Night Football, Hill threw the first interception of the Chiefs' season on a failed trick play in a 29–19 home win. In the subsequent Week 9 game against the Dallas Cowboys, he scored a 56-yard touchdown pass from Alex Smith on an unconventional end-of-half play. As time in the second quarter expired, the Chiefs lined up as if they were going for a Hail Mary pass. Smith threw a checkdown pass to Hill, who had a convoy of blockers clear enough space for him to maneuver to the end zone for the touchdown. However, Dallas scored an un-answered 14 points throughout the second half as Kansas City lost 17–28. During Week 13 against the New York Jets, Hill had a season-high 185 receiving yards on six receptions and two touchdowns, which included a 79-yard touchdown. However, the Chiefs lost on the road by a score of 31–38, Kansas City's last loss in four consecutive games. On December 19, Hill was named to his second consecutive Pro Bowl as a return specialist.
Hill finished his second professional season with 75 receptions for 1,183 yards and seven touchdowns in 15 games and 13 starts. In addition, he had 25 punt returns for 204 yards and a return touchdown.
The Chiefs finished the 2017 season atop the AFC West with a 10–6 record and made the playoffs. In the narrow 21–22 loss to the Tennessee Titans in the Wild Card Round, Hill finished with seven receptions for 87 yards and a single 14-yard rush. He was ranked 40th by his fellow players on the NFL Top 100 Players of 2018.
During Week 1 of the 2018 season against the Los Angeles Chargers, Hill ran his first punt return of the season 91 yards for a touchdown. He also had 7 receptions for 169 yards and two receiving touchdowns as the Chiefs won 38–28 on the road.

On April 26, 2019, Chiefs general manager Brett Veach announced that Hill was suspended from team activities as a result of the ongoing child abuse investigation. The NFL announced on July 19 that he will not be disciplined for the investigation because the league felt he did not violate the personal conduct policy. On September 6, Hill signed a three-year, $54 million extension.
In the season opener against the Jacksonville Jaguars, Hill injured his shoulder and was taken to the hospital as a precaution. Later in the day, it was revealed he had a posteriorly dislocated sternoclavicular joint and would "miss some time". Hill made his return from injury during Week 6 against the Texans, where he caught five passes for 80 yards and two receiving touchdowns in the 24–31 loss. In the next game against the Broncos, Hill finished with 3 receptions for 74 yards, including a 57-yard touchdown pass, as the Chiefs won on the road by a score of 30–6.
