State Highway 199, also known as SH-199 or , is a 44.0-mile (70.8 km) highway in southern Oklahoma. The highway connects Ardmore to Madill as a more northerly alternate to US-70, much of which SH-199 is an old alignment of. It provides access to the Fort Washita Historic Site.

The highway's western beginning is at I-35 exit 31 in Ardmore. At this cloverleaf interchange, eastbound US-70 joins southbound I-35 in a concurrency. SH-199 continues the alignment of US-70 along W. Broadway Street into Ardmore. At Commerce Street, the highway intersects US-77. SH-199 continues east along Broadway into downtown, where the highway splits along a one-way pair; westbound SH-199 follows W. Broadway, while eastbound traffic is shunted onto W. Main Street. SH-199 turns north along Washington Street and follows it to Sam Noble Parkway, where it turns back to the east. As it leaves town, it serves as the eastern terminus of SH-142.

After leaving Ardmore, the highway continues along a due east course that takes it through the unincorporated places of Dripping Springs and Caldwell Hill. At Dickson it becomes concurrent with US-177. Shortly after this junction, the two highways cross into Johnston County, where they pass through the town of Mannsville. The routes then turn southeast into Marshall County. Just after the county line lies the southern terminus of SH-1, which leads back into Johnston County.
