Karl Bertil Emanuel Nordahl (26 July 1917 – 1 December 1998) was a Swedish footballer who played as a midfielder. He was also a football manager.
He played for Degerfors IF and Atalanta B.C.[2] He won the gold medal at the 1948 Summer Olympics, along with his brothers Knut and Gunnar Nordahl.[3] After the Olympics, he and Gunnar transferred to Italy and, due to being in a professional football league while the Swedish football was all amateur, they were not called to the 1950 FIFA World Cup.[4] He was capped 15 times for the Sweden men's national football team.
After his playing career, he coached Örebro SK and IK Brage.[5]
