Egil Yngvar Olbjørn (3 August 1902 – 1 February 1982) was a Norwegian police leader.
He came to prominence during the occupation of Norway by Nazi Germany, as a member of Nasjonal Samling and supporter of Jonas Lie.
To a certain degree he tried to resist German control, and was imprisoned for a short period in the autumn of 1944.
