State Highway 66 (abbreviated SH-66) is a 192.7-mile (310.1 km) state highway in the U.S. state of Oklahoma, beginning at U.S. Highway 81 in El Reno and ending at U.S. Highway 60 near White Oak. The highway was designated in 1985 as a replacement for the decommissioned US-66. Although most of the highway follows Historic Route 66, the highway follows US-66's final alignment, joining Interstate 44 through Tulsa and Oklahoma City, while older versions of the route follow various city streets through both cities.

The highway has retained its importance for most of its length due to its paralleling Interstate 44 which between Missouri and Oklahoma City (except in the cities of Tulsa and Oklahoma City) is a toll road.

SH-66 currently has one spur route, designated SH-66B, in Wellston.

State Highway 66 begins at Business I-40 in El Reno (another old Route 66 segment), concurrent at this point with US-81. From this intersection, the highway heads due east. The highway briefly passes through a rural area after leaving El Reno, before transitioning into the Oklahoma City suburb of Yukon. In Yukon, the route runs along Main Street, and has a short concurrency with SH-4. SH-66 continues east, passing into Oklahoma City, where it becomes N.W. 39th Expressway. SH-66 has an interchange with the Kilpatrick Turnpike on the far west edge of the city. The highway passes just to the north of Lake Overholser. Near where the road crosses over the North Canadian River, the inlet to the lake, it crosses from Canadian County into Oklahoma County.
