State Highway 51, abbreviated to SH-51 or OK-51, is a major state highway in Oklahoma. It runs for 333 miles[1] (535½ km) east–west across the state, running from the Texas state line to Arkansas. It is the third-longest state highway in the system.

SH-51 begins at the Texas line concurrent with US-60 just east of Higgins, Texas. It remains concurrent for 61 miles (98 km) until it reaches US-270/US-281/SH-3 at Seiling, Oklahoma. At Seiling, SH-51 joins with those three highways for nine miles (14 km) before splitting off on its own.
11 miles (18 km) after splitting off, Highway 51 meets SH-58 in Canton. It then continues east, crossing the North Canadian River and meeting SH-51A before turning northeast toward Okeene, where it intersects SH-8. SH-51 will go for 24 miles (39 km) before intersecting another highway.
In Hennessey SH-51 meets U.S. Highway 81 before continuing eastward. 17 miles (27 km) later, it meets SH-74 north of Crescent. 11 miles (17 km) to the east, it shares a brief concurrency with US-77; two miles (3 km) later it has an interchange at Interstate 35, milemarker 174.
After crossing I-35, SH-51 becomes a multilane highway and a major corridor linking I-35 to Stillwater, the home of Oklahoma State University. Along this 13-mile (21 km) stretch is an intersection with State Highway 86. When Highway 51 reaches Stillwater, it meets US-177.
Continuing east from Stillwater, the road returns to a two-lane highway after sharing a one-mile (1.6 km) concurrency with SH-108 and intersects with SH-18 eight miles (12.8 km) later. Four miles east of this, it passes through Yale, Oklahoma before crossing SH-99. It becomes a multilane highway again after a brief concurrency with SH-48. It passes through the small towns of Mannford and Lotsee on its way toward the Tulsa area.
In Sand Springs, SH-51 crosses the Arkansas River with SH-97 before merging onto the Sand Springs Expressway (U.S. Highway 412/U.S. Highway 64). When this freeway ends at I-244 near downtown Tulsa, Highway 51 merges onto I-244 southbound only to exit one mile (1.6 km) later, where it overlaps US-64/US-75. This freeway is actually Interstate 444, but the interstate designation is not shown on signs. After one more mile, SH-51 leaves the interstate with US-64 and becomes the Broken Arrow Expressway, a freeway running northwest-southeast through Tulsa. US-64 leaves the freeway as a concurrency with US-169 southbound. Later, SH-51 will exit the freeway and become a four lane highway toward Coweta. The mainline freeway becomes the Muskogee Turnpike.
At Coweta, SH-51 turns back east after heading southeast through the Tulsa area. After crossing the Muskogee Turnpike again and bridging the Verdigris River the highway soon enters Wagoner, where it junctions with US-69. Returning once again to a 2-lane road, Highway 51 crosses Ft. Gibson Lake and the town of Hulbert. 11 miles (18 km) later, it passes through Tahlequah, where it has a brief concurrency with US-62/SH-10. After spitting with these highways, it heads southeast toward Stilwell, Oklahoma, overlapping Route 59 for a mile on the way. After leaving Stilwell it provides access to Adair State Park, and then crosses the Arkansas line becoming Highway 244, which quickly connects to Highway 59.
SH-51 was originally commissioned on June 1, 1927 as a connector from Stilwell to Eldon at SH-27 (present-day US-62).[2] By 1928, it had been extended to Tulsa.[3] On June 15, 1933, it was extended to the east to the Arkansas state line, where it became AR-45.[2]
ODOT extended SH-51 west to Stillwater and Perry (via a segment of roadway currently serving as US-177).[2][4] On March 18, 1935, the section from Stillwater to Perry was rescinded and SH-51 was extended to SH-8 at Okeene.[2][5] It was then extended to Seiling on October 18, 1938. On March 23, 1943, it was extended to the Texas state line by a concurrency with US-60.[2]
The Broken Arrow Expressway was built in the early 1960s[6] and opened in 1964.[2] It was not, however, officially named the Broken Arrow Expressway until July 6, 1999 [7] by H.B. 1455.
The steel truss bridge carrying SH-51 across Stillwater Creek west of Stillwater, once considered the gateway into the city, was removed on March 25, 2008. In a first for the state of Oklahoma, the bridge, originally built in 1936, was sold to Payne County for $200,000 and transferred to a county road east of Stillwater, where it was installed over Council Creek.[8]
Like many in the Oklahoma state highway system, SH-51 has short spurs branching from it that bear the "51" number with a lettered suffix:
