Erik Johan Mattias "Notan" Norström (born 2 January 1972) is a Swedish former professional ice hockey defenceman, currently working for the AIK organization.

On 14 March 1996, he was traded with Nathan LaFayette, Ian Laperrière, Ray Ferraro and a draft pick to the Los Angeles Kings for Marty McSorley, Jari Kurri and Shane Churla.

Norström was originally appointed to the Swedish national team for the 2006 Olympic Games in Turin but had to withdraw due to injury.

Blake refused at his presentation press conference and told the media that he regarded "Matty" as the obvious captain and the "core and soul" of the Kings.
