Highway 16A is the designation of three alternate routes off Alberta Highway 16 (the Yellowhead highway) in Alberta, Canada. The Evansburg – Entwistle section is called 16A:08 by Alberta Transportation, while 16A:24 runs through Vegreville. The section west of Edmonton is labelled 16A:14 and 16A:16 on Alberta Transportation maps, but is better known as Parkland Highway and Stony Plain Road.

Highway 16A:08 parallels Highway 16 to the north, intersecting Highway 22, and passing through Evansburg, Pembina River Provincial Park, and Entwistle.

Running for 35 km (22 mi), the Parkland Highway (Highway 16A) runs parallel to Highway 16, 3.2 km (2.0 mi) to the north. The highway starts west of Stony Plain near the hamlet of Carvel. Parkland Highway is a central thoroughfare through the bedroom communities of Stony Plain and Spruce Grove. At Acheson it has a partial cloverleaf interchange with Highway 60. Highway 16A enters Edmonton along Stony Plain Road, splits into one-way streets where eastbound traffic follows 100 Avenue, before ending at Anthony Henday Drive (Highway 216).

Highway 16A and the Parkland Highway were established in 1997 when the Highway 16 designation was moved to Highway 16X, a bypass route that becomes Yellowhead Trail in Edmonton.

All exits are unnumbered.

Highway 16A:24 runs through the Town of Vegreville as 50 Avenue.
