State Road 263 is a business route of State Road 63 which runs through West Lebanon in Warren County, covering a distance of about 13 miles (21 km).

It is an undivided two-lane surface road for its entire length.

Upon reaching the south edge of West Lebanon (the portion locally known as "Old Town"), State Road 263 is concurrent with High Street; it crosses a Norfolk Southern railway in the north part of town and intersects State Road 28 at the north edge of town.

The remaining portion of the highway runs through open country and passes just to the east of Seeger Memorial Junior-Senior High School and Warren Central Elementary School, and finally rejoins State Road 63 about a mile further north, just beyond Division Road.

The new four-lane divided highway was constructed to the west in the early 1970s and was often called "New 63" by residents of the area; the resulting business route officially named State Road 263 was often called "Old 63".
