Björn Tom Wesström (born 11 September 1972) is a Swedish football executive and manager who was recently the assistant coach of the Indian Super League club Kerala Blasters.

[3] Under their management, Väsby United achieved a second-place finish in the league, securing promotion to the Superettan, the second-tier of Swedish football.

[6] In the early stages of the 2010 season, Mikael Stahre resigned as the club's head coach and as a result,[7] Wesström was appointed as the caretaker manager of AIK on 26 April 2010 with immediate effect.

[10] After a series of disappointing results, and due to the club's failure for securing the UEFA coaching license for Wesström for managing the team in the 2010–11 UEFA Champions League second qualifying round,[11] the club appointed Alex Miller as their new head coach and Wesström was appointed as his assistant for the rest of the season.

[21] Just days after getting sacked by Odense Boldklub, on 7 June 2024, Wesström was appointed as the assistant coach of the Indian Super League club Kerala Blasters FC.
