Kenmore station is a light rail station on the MBTA Green Line, located under Kenmore Square in the Fenway/Kenmore neighborhood of Boston, Massachusetts, United States. The station opened on October 23, 1932 as a one-station extension of the Boylston Street subway to relieve congestion in the square. Kenmore is the primary station for passengers wishing to visit Fenway Park, located one block away.

The Green Line is a semi-metro system run by the Massachusetts Bay Transportation Authority (MBTA) in the Boston, Massachusetts, metropolitan area. It is the oldest MBTA subway line, and with tunnel sections dating from 1897, the oldest subway in North America. It runs underground through downtown Boston, and on the surface into inner suburbs via six branches on radial boulevards and grade-separated alignments. With an average daily weekday ridership of 137,700 in 2019, it is the third-most heavily used light rail system in the country. The line was assigned the green color in 1967 during a systemwide rebranding because several branches pass through sections of the Emerald Necklace of Boston.
