Stadion is a Stockholm subway station on the red line, route 14. Its cave walls are painted bright blue, with a multicoloured rainbow across them. Artists Åke Pallarp and Enno Hallek made the station art to bring the sky underground and recall the area's sports history.

The station was built in 1973 as one of Stockholm's first cave stations. The design was controversial: art guide Marie Andersson says people feared cave stations might be associated with the netherworld and other unpleasant places. The blue walls and rainbow were intended to suggest that the sky was close above.

Stadion is near Östermalms IP, which serves as the main site for Stockholm Pride each year. The rainbow at the station welcomes festival-goers, according to Visit Stockholm.

The station is close to Stockholm Olympic Stadium, where the 1912 Olympics took place and Swedish bandy finals were held each year from 1913 through 1965. The stadium still hosts sports events and concerts.
