Ueno Park (上野公園, Ueno Kōen^?) is a spacious public park in the Ueno district of Taitō, Tokyo, Japan. The park was established in 1873 on lands formerly belonging to the temple of Kan'ei-ji. Amongst the country's first public parks, it was founded following the western example as part of the borrowing and assimilation of international practices that characterizes the early Meiji period. The home of a number of major museums, Ueno Park is also celebrated in spring for its cherry blossoms and hanami. In recent times the park and its attractions have drawn over ten million visitors a year, making it Japan's most popular city park.

Ueno Park occupies land once belonging to Kan'ei-ji, founded in 1625 in the "demon gate", the unlucky direction to the northeast of Edo Castle. Most of the temple buildings were destroyed in the Battle of Ueno in 1868 during the Boshin War, when the forces of the Tokugawa shogunate were defeated by those aiming at the restoration of imperial rule. In December of that year Ueno Hill became the property of the city of Tokyo, other than for the surviving temple buildings which include the five-storey pagoda of 1639, the Kiyomizu Kannondō (or Shimizudō) of 1631, and approximately coeval main gate (all ICPs).
