Nebraska Highway 133 (N-133) is a state highway in Douglas and Washington counties in Nebraska, United States, that conencts U.S. Route 6 (US 6) in Omaha with U.S. Route 30 (US 30) in Blair. For its entire length, N-133 is a four-lane divided highway.

N-133 begins at a signal-controlled intersection with US 6 (Grand Army of the Republic/West Dodge Road) and North 90th Street in Omaha in Douglas County. (From the intersection US 6 heads east toward Interstate 480/U.S. Route 75 and Downtown Omaha and then on to Council Bluffs, Oakland, and Atlantic in Iowa. US 6 heads west toward Interstate 680, Boys Town, Gretna, and Lincoln. North 90th Street heads south for several miles in Omaha.) From its southern terminus N-133 heads north along North 90th Street through residential and commercial areas for one and a half miles (2.4 km) before crossing Nebraska Highway 64 (N-64/Maple Street) at a signal-controlled intersection. (N-64 heads east to end at U.S. Route 75 and west toward U.S. Route 275, Waterloo, and Valley.)

North of N-64, N-133 continues north along North 90th Street for just under 2 miles (3.2 km) before reaching a signal-controlled intersection with Nebraska Link 28K (L-28K/Blair High Road) and Sorensen Parkway at a signal-controlled intersection near the northern edge of Omaha and just south of Irvington. (L-28K heads southeast to end at N-64. Sorensen Parkway heads north, then east to end at US 75. From 1955 to 1960, what is now L-28K, was designated as Nebraska Highway 38.) From that intersection N-133 heads northwest along Blair High Road for just over one mile (1.6 km) to a junction with Interstate 680 (I-680) at a diamond interchange (I-680 Exit 6) before leaving Omaha. (I-680 heads east toward US 75 and then on to Interstate 29 and Crescent in Iowa. I-680 heads south toward US 6, N-64, and Interstate 80.)

After leaving Omaha, N-133 continues north–northeasterly along Blair High Road in rural area in an unincorporated area of Douglas County for about 3.3 miles (5.3 km) to cross Nebraska Highway 36 (N-36/Bennington Road) at a signal-controlled intersection. (N-36 heads east along Bennington Road toward Omaha, US 75, and I-680 and west along Bennington Road toward Bennington and Fremont.) North of N-36, N-133 continues north–northeasterly along Blair High Road for approximately 2 miles (3.2 km) before crossing Dutch Hall Road.

Upon crossing Dutch Hall Road, N-133 leaves Douglas County and enters Washington County. After continuing north for roughly 1.2 miles (1.9 km), N-133 curves to head northwest along the northern edge of the Blair Municipal Airport. Beyond the airport, N-133 continues heading north–northwest for roughly another 4.2 miles (6.8 km) before curving to head northerly again. After approximately 2.3 miles (3.7 km), N-133 enters the city of Blair. Shortly thereafter (0.3 miles [0.48 km]) N-133 reaches its northern terminus at a roundabout with US 30. (From the roundabout US 30 heads north, then east through Blair toward Missouri Valley in Iowa. US 30 heads southwest through Kennard and then west toward Fremont.)

N-133 was established by 1947.
