Arkansas Highway 133 (AR 133, Hwy. 133) is a designation for three state highways in South Arkansas. One route of 24.20 miles (38.95 km) runs from Louisiana Highway 142 north through Crossett to Highway 8 near Fountain Hill. A second segment runs from Highway 160 north to US Route 425 (US 425) at Lacey. A third segment begins in Rison at Highway 35 and runs north to Highway 54 south of Pine Bluff.

The route begins at Louisiana Highway 142 at the Louisiana state line and runs north through rural Ashely County. It passes by three properties on the National Register of Historic Places (NRHP) near the Arkansas Forest Commission building: Crossett Experimental Forest Building No. 2, Building No. 6, and Building No. 8. Entering Crossett the highway becomes Main Street and passes by several properties on the National Register including the Municipal Auditorium, Municipal Building, Methodist Church, and Post Office. Highway 133 also has a junction with Highway 133 Truck, which gives access to US 82 as a truck route through Crossett. The highway intersects US 82, forming a concurrency east for five blocks.

After the concurrency ends Highway 133 continues north to North Crossett where it meets Highway 133 Spur near an industrial area and Highway 52. The highway continues through wooded areas as an alternating passing lane highway, including a junction Highway 189 near Old Milo. Continuing north the route terminates at Highway 8 near Fountain Hill.

Highway 133 begins at Highway 160 west of Fountain Hill and runs northeast through heavily forested country. The route terminates at US 425 at Lacey in south Drew County. Highway 133 does not have any intersections with other state highways between its termini. Traffic counts from the Arkansas State Highway and Transportation Department (AHTD) from 2010 indicate that this segment of state highway averages 360 vehicles per day (VPD).

The highway begins in Rison at Highway 35 near the Rison Cities Service Station. Highway 133 runs north as Magnolia Street past the Hall Morgan Post 83, American Legion Hut and the Cleveland County Courthouse before exiting Rison to the northeast. Winding northeast through forested land the route enters Jefferson County and terminates at Highway 54.

Traffic counts from the AHTD from 2010 show that an average of 890 vehicles per day use Highway 133 in the city limits of Rison. The traffic average drops once outside of town, as low as 750 VPD near the northern terminus.
