On April 30, 2015, Shelton was drafted by the Cleveland Browns with the 12th overall selection of the first round in the 2015 NFL Draft. When meeting with Roger Goodell on stage, he hugged the commissioner and lifted him off the ground in excitement. Shelton was the University of Washington's first defensive lineman selected in the first round of a NFL draft since Steve Emtman in 1992. On May 12, 2015, Shelton signed a four-year deal worth $11.7 million.   In 16 games of his rookie season, Shelton played 16 games with 36 tackles.
After center Alex Mack left the team in free agency during the 2016 offseason, Shelton changed his jersey number from 71 to 55, which was previously worn by Mack.  Shelton had wanted the number since being drafted by the Browns but opted for his college 71 since 55 was unavailable. He explained he wanted to adorn 55 as tributes to his brother Shennon and former NFL linebacker Junior Seau, both of whom have died and have worn 55 while playing football.  In 2016, he started all 16 games with 59 tackles and 1.5 sacks.
On February 23, 2017, Shelton underwent a minor wrist surgery. 
On May 1, 2011, Shelton and his brothers were involved in an altercation at an apartment complex in Auburn, Washington. According to a release, Shelton's brother, Gaston Shelton, was at a friend's apartment when a fight between a group of men broke out. While Gaston was recording the incident on his cell phone he was punched and struck the man back. Three men, including a man named Olenthis Woods, assaulted Gaston causing multiple cuts. After the attack, Gaston called his wife and told her to tell Danny and his brothers that he was jumped. Danny and his brothers Kevin and Shennon then arrived at the complex along with a cousin and a friend. The six men then began to search for Olenthis Woods. After they approached his home, Woods' mother and sister attempted to have them leave while Woods himself went inside his home to retrieve a handgun. Gaston and Shennon Shelton stood at the front door while the others surrounded the sides of the house. Woods then shot Gaston Shelton in the chest after telling him to back up. Shennon Shelton then lunged at Woods and was shot in the head, causing his death. Although Gaston would survive, Auburn prosecutors decided not to charge Olenthis Woods, deeming his actions to be in self-defense.
