Tolka Valley Park (Irish: Páirc Ghleann na Tulchann)[1] is a public park on the River Tolka, spanning the suburbs of Ashtown, Finglas and Glasnevin, in Dublin, Ireland.

[2] These "integrated constructed wetlands" were built at the confluence between the Finglaswood Stream and River Tolka, and designed to improve water quality and reduce pollution in the watercourse.

[4][5] Sections of the River Tolka, within the park, have been stocked with salmon and trout.

[9][10] The eastern section of Tolka Valley Park, within the Dublin City Council authority area, spans westward from the Finglas Road in Glasnevin via Finglas to Ashtown.

[11][2] A further section, sometimes referred to as "Tolka Valley Linear Park" or "Tolka Valley Regional Park",[12] extends into the Fingal County Council authority area, westwards from Blanchardstown to Mulhuddart.
