After Dunbar went undrafted in the 2015 NFL draft, he signed a three-year contract with the Washington Redskins on May 11, 2015.[6][7] Dunbar entered training camp as a backup wide receiver and special teams' player, competing for a roster spot. On August 7, it was reported that the Redskins decided to change Dunbar's position from wide receiver to cornerback. He was moved to cornerback after coaches recognized his ability to successfully block (or "jam") return specialists during punt returns. The position change was also due to multiple injuries in the Redskins' secondary, as well as to give Dunbar a better opportunity to make the roster.[8] In a corresponding move, Dunbar changed his jersey number from No. 17 to No. 47.[9]
On October 4, Dunbar made his professional regular season debut during the Redskins' 23–20 win against the Philadelphia Eagles in Week 4. He was inactive for the Redskins' Week 10 win against the New Orleans Saints as a healthy scratch. In November, Dunbar became the third cornerback on the depth chart after the Redskins decided to move cornerback Hall to safety and placed Culliver on injured reserve with a torn ACL and MCL.[14] On November 29, Dunbar recorded two solo tackles, deflected two passes, and made his first career interception during a 20–14 victory against the New York Giants in Week 12. He made his first career interception off a pass by Giants' quarterback Eli Manning in the end zone, but exited the game shortly thereafter due to a dislocated finger.[15] In Week 14, Dunbar earned his first career start and made two combined tackles in a 24–21 win at the Chicago Bears.[16] He was inactive for the Redskins' Week 17 win at the Dallas Cowboys as a healthy scratch. HC Gruden decided to rest him, along with multiple starters, as the Redskins had already clinched a playoff berth with a 9–7 record. He finished his rookie season in 2015 with 13 combined tackles (11 solo), five pass deflections, and an interception in 11 games with two starts.[17]
On January 10, 2016, Dunbar appeared in his first career playoff game; he made five solo tackles and broke up two passes in the Redskins' 35–18 loss to the Green Bay Packers in the NFC wild card Game.[16]

On December 19, 2016, Dunbar deflected two passes, made one tackle, and made his first career sack on Panthers' quarterback Cam Newton in the Redskins' 26–15 loss to the Carolina Panthers in Week 15.[21] He exited the game in the third quarter after suffering a concussion and was sidelined for the last two games (Weeks 16–17).[22][23] Dunbar finished the 2016 NFL season with 26 combined tackles (23 solo), five pass deflections, one interception, and a sack in 14 games and two starts.[17]

In Week 6, he collected a season-high eight combined tackles and deflected two pass during a 26–24 victory against the San Francisco 49ers.
