Arkansas Highway 27 (AR 27) is a designation for four state highways in Arkansas. One segment of 58.30 miles (93.82 km) runs from US 59/US 71 west of Ben Lomond north to US 270 in Mount Ida. A second segment of 46.09 miles (74.17 km) runs from US 270 west of Mount Ida north to Highway 10 in Danville. A third segment of 18.41 miles (29.63 km) runs from Highway 10 in Danville north to Highway 7 in Dardanelle. A fourth segment of 71.98 miles (115.84 km) runs from Highway 7 in Dover north to Highway 14 at Harriet.

The designation also includes Highway 27B, a business route in Nashville, and Highway 27N, a former alternate route near Ben Lomond deleted in the 1990s. All highways are maintained by the Arkansas State Highway and Transportation Department (AHTD).

Highway 27 begins at US 59/US 71 west of Ben Lomond. The route runs east, meeting Highway 317 before meeting Highway 355 in Mineral Springs. The route continues to Nashville where it meets US 278 and US 371/Highway 24. North of Nashville, Highway 27 meets Highway 26 until Murfreesboro, when it picks up Highway 19.

The route winds north to meet US 70/Highway 84 in Kirby. Highway 27 follows US 70 until Glenwood, when it meets Highway 8 and enters the Ouachita National Forest. The two routes run together until Norman. Highway 27 continues northeast to US 270 in Mount Ida, where it terminates.

The route begins at US 270 and Highway 379 west of Mount Ida and runs north to Washita, where it meets Highway 298. Highway 27 eventually leaves the forest near Rover, which contains a junction with Highway 28. The route meets Highway 10 in Danville, where it terminates.

The route begins at Highway 10 in Danville and runs north to Dardanelle, where it terminates at Highway 7 and Highway 22 on the south edge of town.

The route begins at Highway 7 in Dover and winds northward for a stretch, eventually meeting Highway 16 and Highway 333 in rural Searcy County. Highway 27 continues northeast to meet US 65/Highway 74 in Marshall. After Marshall, the route trails north to Highway 14 in Harriet, where it terminates.

Highway 27 was created during the 1926 Arkansas state highway numbering as an original state highway between Ben Lomond and Harriet. The segment between Highway 28 at Rover and Highway 10 in Danville was deleted in 1929, but it was restored in 1931.

Following construction of new terrain routes for Highway 7 and Highway 22, Highway 27 was truncated at the new alignment of Highway 7 in Dardanelle. This action separated the highway into its two present-day sections.

The highway was completed to Marshall on March 11, 1954, to Mount Ida on June 27, 1962., between Hector and Tilly on March 24, 1971, and between Ben Lomond and Mineral Springs on September 29, 1976.
