Arkansas Highway 226 is a designation for two state highways in northeast Arkansas. The main segment of 25.28 miles (40.68 km) runs east from an intersection of U.S. Route 67/Arkansas Highway 367 to future I-555/US 63/AR 18 in Jonesboro. A short route of 2.38 miles (3.83 km) runs in rural Jackson County west of Tuckerman.

AR 226 runs east from Jackson CR 278 to cross AR 17 to AR 37, where it terminates.

The route then runs due east near Swifton through AR 18 in Cash, also meeting AR 349 near Jonesboro. Highway 226 winds into Jonesboro, meeting US 63/AR 18 and terminating. US 67 traffic is currently routed onto AR 226 while the AHTD continues to build US 67 to interstate standards. The limited access portion of US 67 currently ends at AR 226 between Cash and Swifton, and AR 226 is being used to redirect traffic from the new route to the old alignment. The route is two-lane undivided for its entire length, passing through flat, square farmland for most of its length.

The route became a state highway in 1958, running from an area south of Swifton east to Gibson. AR 226 later later was extended to Jonesboro, including a concurrency with Arkansas Highway 39 (now US 49). When US 49 replaced AR 39 around 1980, AR 226 was split into its current alignment and AR 226S. The short Jackson County segment was added to the system in 1996.

Arkansas Highway 226 Spur is a spur route in Jonesboro. Known locally as Wood Springs Road, the routes is1.03 miles (1.66 km) in length.

The entire route is in Jonesboro, Craighead County.
