Nairn Falls Provincial Park, Provincial park in Squamish-Lillooet Regional District, British Columbia, Canada

Nairn Falls Provincial Park is a 170-hectare provincial park on the Green River beside Highway 99 and the Canadian National Railway line, south of Pemberton. Its centrepiece, Nairn Falls, is a tiered waterfall 39.6 metres high and 9.1 metres wide on average, throttled by a small canyon before the Green River reaches the Pemberton Valley lowlands and joins the Lillooet River. The forest is coastal western hemlock, with western hemlock, Douglas fir and western redcedar.

Nairn Falls Provincial Park was established in 1966, shortly after Highway 99 opened through the corridor, to protect and improve visitor access to Nairn Falls. The 170-hectare protected area lies on the Green River beside the highway and the Canadian National Railway line, just south of Pemberton and under twenty minutes north of Whistler.

The park lies within an area of cultural importance to the Lillooet (St'at'imc) people, a First Nations group. The falls are known in the Lillooet language as Skweskwistqw7am, pronounced roughly "shkweshkweshtqw'em".

The park offers roughly 94 vehicle-accessible camping sites open from May through October. Advance reservations are helpful during busy periods to secure your spot.

The Lillooet name for the falls and park is Skweskwistqw7am, pronounced roughly shkweshkweshtqw'em. The falls sit in a small canyon that narrows the Green River just before it reaches the lowlands of the Pemberton Valley and joins the Lillooet River above its estuary into Lillooet Lake.
