Assomption station is a Montreal Metro station situated in the Mercier–Hochelaga-Maisonneuve borough of Montreal, Quebec. Managed by the Société de transport de Montréal (STM), it facilitates commuters along the Green Line and resides within the Hochelaga-Maisonneuve district. The station opened some time after 6 June 1976, as part of the extension of the Green Line to Honoré-Beaugrand.

Designed by Duplessis and Labelle, Assomption station features a conventional side platform layout constructed primarily from concrete and partially situated within a tunnel. Access to the station is facilitated through a deep open cut that leads to a single entrance. Notably, the station's entrance building and the hallways leading to the stairwell have murals painted by Guy Montpetit.

In 2022, the STM's Universal Accessibility Report noted that preliminary design work to make the station accessible was underway.

This station, formerly known as L'Assomption, (a name that can still be observed on the station's nameplates), derives its name from Assomption boulevard. The boulevard was named as such in 1951, commemorating Pope Pius XII's affirmation of the dogma of the Assumption of Mary in his 1950 apostolic constitution, Munificentissimus Deus.
