Esplanadi  colloquially known as Espa, is an esplanade and urban park in downtown Helsinki, Finland, situated between the Erottaja square and the Market Square. It is bordered on its northern and southern sides by the Pohjoisesplanadi (North Esplanadi) and Eteläesplanadi (South Esplanadi) streets, respectively. Aleksanterinkatu runs parallel to Esplanadi. Esplanadi is well-known as a popular walking area, and street performances are also often held in the park.

Designed by the architect Carl Ludwig Engel, the park was originally opened in 1818. In 1827, Engels Teater (the predecessor of the Swedish Theatre), the first theatre building in Helsinki, also designed by Engel, was erected in a corner of the park.The Esplanadi park; on the left the statue of Johan Ludvig Runeberg

The eastern end of the park houses the Kappeli restaurant, which opened in 1867. In front of the restaurant is an outdoor stage, which hosts numerous live music performances. Centered in the park is a statue of Johan Ludvig Runeberg, the national poet of Finland, by his son Walter Runeberg. Other public art pieces include works by Viktor Jansson, Gunnar Finne and Lauri Leppänen.
