Björn Hellberg (born 4 August 1944) is a Swedish sports journalist, author, tennis oracle and TV personality, best known as co-host and referee of the television show "På spåret". He was born in Borås, Sweden, but his family soon moved to Laholm. Although he participated as a competitor during the early years of "På spåret", later (in the team in which Bengt Grive and Mats Strandberg also participated), he turned out to be an "oracle" in all possible subjects outside tennis, his absolute favorite subject.
