The A4148 is an A-class road in the town of Walsall, West Midlands, England. It serves as the town's ring road, as it encircles the town centre, and no road inside it has a number. Major junctions occur where it meets the A34, A454 and A461.
Rather than a purpose-built ring road, such as the nearby Wolverhampton Ring Road, the A4148 consists of existing streets marked as a ring road. Since 2006, Walsall Council has implemented a number of roadwork projects in an attempt to improve traffic flow.
