The nihongo|Sannō Park Tower|山王パークタワー|Sannō Pāku Tawā is a 44-storey skyscraper located in Chiyoda, Tokyo, Japan. It is the second highest building of the ward, after the Shin-Marunouchi Building.

The top floors are occupied by the head offices of the largest mobile carrier in Japan, NTT DoCoMo.The lower floors house several multinational corporations, such as Deutsche Bank Securities.The "Skylobby" at the 27th floor has restaurants and a closed observation deck.

Just at the foot of the Hie Shrine, the skyscraper overlooks directly both the Prime Minister of Japan's official residence (Sōri Kantei) and the Diet Building.As a consequence, windows of the tower in the direction of the Prime Minister's residence are all locked, and there are no windows on the residence side giving in the Park Tower direction.To achieve such a height in such a strategical location, air rights were bought from the neighbouring Hie Shrine.

The building stands over Tameike-Sannō Station which is served by the Tokyo Metro Ginza Line (G06), Tokyo Metro Namboku Line (N06) and linked to Kokkai-gijidō-mae Station (M14) on the Tokyo Metro Marunouchi Line.
