Tervel Ivaylov Dlagnev (Bulgarian: Тервел Ивайлов Длагнев, born November 19, 1985) is an American freestyle wrestler, who represented the United States in the 125 kg weight division.

[1][3] Dlagnev only wrestled three years in high school, where he finished fourth and third at the Texas state championships in 2002 and 2003.

[8] During the wrestling competition at the 2012 Summer Olympics, Dlagnev finished in fifth place after he was pinned by Artur Taymazov from Uzbekistan in the semi-final and suffered a loss against Komeil Ghasemi from Iran in his bronze medal bout due to separated cartilage in his rib cage.

[9] On 23 July 2019 it was announced that as a result of retesting samples, Artur Taymazov had been disqualified from the 2012 Olympics for a drug violation, and his gold medal from that event also withdrawn.

Dlagnev had originally finished fifth, but Davit Modzmanashvili was also stripped of his silver earlier in the year due to doping.
