Else-Marthe Sørlie Lybekk (née Sørlie; born 11 September 1978, in Gjøvik) is a retired Norwegian team handball player, world champion from 1999, gold medalist from the 2008 Summer Olympics in Beijing, and bronze medalist from the 2000 Olympics.

[1] She is also a triple European champion with the Norwegian national team, which she previously captained prior to the reign of fellow Gjøvik handballer Gro Hammerseng.

2 November 1997, Sørlie Lybekk debuted in a friendly against Germany, marking the beginning of a long career for the Norwegian side.

The first highpoint in her international career is the victory in the 1999 World Championships held on home turf (alongside Denmark) where she was contributing to her nation's win mostly in the defensive side of the game.

The playing style is efficient, but not as spectacular as other notable players in her generation of Norwegian handballers.
