Meiji Parkı, Public park in Shinjuku and Shibuya, Tokyo, Japan

Meiji Park is a metropolitan park split by Gaien Nishi-dori into a Shibuya side with Tokyo Metropolitan Gymnasium and an athletics ground, and a Shinjuku side with the Kasumigatake plaza used for flea markets. It opened in 1964 when the National Stadium was prepared as the main venue of the Tokyo Olympics, and it is not under the administration of Meiji Shrine.

Meiji Park opened in 1964, laid out when the National Stadium was chosen as the main venue of the Tokyo Olympics. It sits beside Meiji Jingu Gaien but is not under the shrine's administration. In 2016 the Shiki no Niwa garden and Kazukadake Hiroba were closed, and in October 2023 the Hope, Inclusive, Michi and Pride areas reopened as part of a reorganisation tied to the stadium's 2019 rebuilding.

The park's name comes from Emperor Meiji, though the adjacent Meiji Shrine is not under its administration. The grounds are split by Gaien Nishi-dori: the Shibuya side holds the Tokyo Metropolitan Gymnasium and athletics facilities, while the Shinjuku side has Kasumigatake Plaza, used for flea markets and as a waiting area for spectators at nearby National Stadium events.

The Shibuya-side facilities are about 3 minutes on foot from Sendagaya Station on the JR Chuo-Sobu Line and 2 minutes from Kokuritsu-Kyogijo Station on the Toei Oedo Line; Gaienmae Station on the Tokyo Metro Ginza Line is about 15 minutes away. For the Kasumigatake Hiroba on the Shinjuku side, Gaienmae is closer than either Sendagaya or Kokuritsu-Kyogijo. The Meiji-Koen-mae bus stop serves the Hachiko Bus Jingu-no-Mori route.

The park opened in 1964, the year the National Stadium hosted the Tokyo Olympics, and was developed alongside it. It is not under the jurisdiction of Meiji Shrine, even though it sits next to the shrine's outer garden. In 2012 it hosted the Railway Festival, the only time the event was held outside Hibiya Park.
