Einar "Jeja" Gundersen (20 September 1896 – 29 October 1962) was a Norwegian footballer. He was a centre-forward for Odd, and is regarded as one of Norwegian football's first star players. He played 33 internationals for Norway, and his 26 international goals puts him second on the national team's all-time scoring list.
His nickname Jeja means literally "Me Then", as that was what he wondered as a kid when he wasn't picked for the team.
At club level, Gundersen scored more than 200 goals. He won the Norwegian Cup five times. He was also a member of the Norwegian team that played in the 1920 Olympics, and scored twice in the 3-1 win against England's amateur side.
