U.S. Route 266 (US 266) is a 43.09-mile (69.35 km), east–west U.S. Numbered Highway in Okmulgee, McIntosh, and Muskogee counties in Oklahoma, United States, that connects U.S. Route 62 U.S. Route 75 (US 62/US 75) in Henryetta with U.S. Route 64 (US 64) in Warner. The highway no longer meets the former route of its parent, U.S. Route 66 (US 66), and is closely paralleled by Interstate 40 (I-40), which replaced US 266 (along with accompanying routes US 62 from Oklahoma City to Henryetta and US 64 from Warner to the Arkansas border west of Fort Smith, Arkansas) as the major east–west highway east of Oklahoma City during the 1960s.
