The Spaulding Turnpike is a 33.2-mile (53.4 km) north-south highway in eastern New Hampshire. Nearly its entire length is overlapped by New Hampshire Route 16. Its southern terminus is at the Portsmouth Traffic Circle (Interstate 95 / U.S. Route 1 Bypass) in Portsmouth, a terminus it shares with U.S. Route 4 and NH 16. Its northern terminus is at an interchange with New Hampshire Route 125 in Milton, where NH 16 continues north as a full-access highway.

The Turnpike roughly parallels the Maine border. NH 16 was signed onto the Turnpike in the mid-1990s.

The Turnpike is part of the New Hampshire Turnpike System operated by the New Hampshire Department of Transportation Bureau of Turnpikes. Along with I-95 between the Massachusetts state border and the Portsmouth Circle (Blue Star Turnpike), the two turnpikes are collectively known as the Eastern Turnpike.

The Spaulding Turnpike begins in Portsmouth, at I-95 northbound exit 4. Access from I-95 south and US 1 Bypass is facilitated via exit 5 (Portsmouth Traffic Circle). A northbound-only exit connects with Brady Drive, accessible only from the traffic circle. The Spaulding Turnpike becomes a six-lane freeway concurrent with US 4 and NH 16, with a 50 mph (80 km/h) speed limit. Exit 1 in Newington provides access to Pease International Tradeport and the Newington malls. The Turnpike expands to 4 lanes just north of exit 1.
