Walmley is a suburban village situated in the civil parish of Sutton Coldfield, West Midlands. It lies within the City of Birmingham on its northeastern outer fringe, where it forms part of the Sutton Walmley and Minworth electoral ward. It is in southern Sutton Coldfield, close to Minworth, Erdington, Wylde Green, Pype Hayes and south of Thimble End. It is approximately 7 miles (11.3 km) northeast of Birmingham City Centre. It is the main focus of the Sutton New Hall Birmingham City Council ward.

The origins of Walmley are unknown, however, it is believed it may have formed as a community for workers at the nearby halls of Langley Hall, New Hall Manor, Penns Hall and Peddimore Hall. It may have originally begun at a point near Penns Hall as it had a major influence in the area, employing many for its activities in Penns Mill and other industries. A small community of Langley developed on the Fox Hollies Road and was mentioned in the Domesday Book, however, it was nothing more than a hamlet with no church, inn or community meeting centre.

John Vesey, Bishop of Exeter, played a small role in Walmley's early development through the construction of several buildings in the area. These were some of 51 stone cottages built by the Bishop who was concerned with the deteriorating state of Sutton Coldfield as a whole. One of these cottages was the ford keeper's house on the banks of Plants Brook, which enabled travellers to pass along Wylde Green Road and over the ford in safety. The building is now listed.

Walmley would have developed from a few scattered houses along Walmley Road which was a main commuter route from Sutton Coldfield to Birmingham. To the north were several farms including one built by Bishop Vesey. Most of the properties were built at the junctions with other roads such as Penns Lane and Fox Hollies Road.

Walmley developed in the 19th century into a prominent area of Sutton Coldfield. It became one of four ecclesiastical districts formed from the parish of Sutton Coldfield, with the others being Boldmere, Hill and Sutton Coldfield. Walmley's first church, St John the Evangelist Church, was built in 1845. The ecclesiastical parish of Walmley was formed in 1846 with St John the Evangelist Church becoming the parish church. Walmley developed into a ward of the Sutton Corporation, covering an area of 4,424 of the total 13,030 acres (52.7 km²) of Sutton Coldfield. Despite being part of the Sutton Corporation area, Walmley was incorporated into the Erdington postal area. Walmley Ash, in the southern part of Walmley, was incorporated into the Minworth postal area.

In 1879, Penns railway station was constructed by the Midland Railway Company and, despite being located in Walmley, it was named after Penns.

Towards the end of the century, the population did not change. In 1881, the population was recorded at being 1,301 and the same number was recorded for 1884.

At the turn of the 20th century, Walmley remained a rural village featuring a church, a few houses and an inn (The Fox Inn). Schools began to establish themselves in the area throughout the 1920s and 1930s. New homes were also constructed along the Walmley Road and Penns Lane as a result of ribbon development. During World War II, Walmley housed an Italian prisoner of war camp near Jones Wood.
