Otterspool Promenade is a riverside walk and accompanying area of parkland in the Aigburth and Grassendale districts of Liverpool, England.

Opened in 1950, it was built by landscaping a site that had been used for disposal of household waste, and for spoil from excavation of the Queensway tunnel under the Mersey in the 1920s.

The stated desire of the local authorities was, "Firstly... provide a place where the citizens of Liverpool can enjoy their leisure in pleasant surroundings on the banks of the Mersey estuary.

Secondly... for providing a large area where the essential need to the community for the disposal of its refuse could be met economically and by the use of hygienic and up-to-date methods.

Toward the end of the Otterpool promenade stands the Sitting Bull sculpture by Dhruva Mistry, commissioned for the 1984 International Garden Festival.
