Fredriksdalsbron is a bridge in central Stockholm, Sweden. Serving the light rail line Tvärbanan, it stretches north from the station west of the Gullmarsplan metro station, immediately makes a sharp eastward turn to plunge under two other bridges, Skanstullsbron and Johanneshovsbron, to continue eastward over a viaduct leading down to the station Mårtensdal in the newly built suburb Hammarby sjöstad.
