Romiley is a village in the Metropolitan Borough of Stockport, Greater Manchester, England. Historically part of Cheshire, it borders Marple, Bredbury and Woodley. At the 2021 census, the Bredbury Green and Romiley ward, which also includes Compstall, Bredbury Green and a large part of Bredbury, had a population of 13,700.

Romiley (or Rvmelie in Medieval Latin) is documented in the Domesday Book of 1086 as being predominantly agricultural, with 16 ploughlands (areas defined as 120 acres each) and 9 square leagues of woodland. It had no recorded population.

Romiley's agricultural nature continued during the centuries leading up to the late Victorian era, when it became a residential area with a small district centre.

The Peak Forest Canal flows around the west and south of Romiley. It was completed in 1805. Although much of the canal fell into disuse by the early 1960s, it was restored and subsequently reopened in April 1974.

Romiley was formerly a township and chapelry in the parish of Stockport.

In 1866, Romiley became a separate civil parish; in 1931, it had a population of 3,722.

On 1 April 1936, the parish was abolished to form the Bredbury and Romiley Urban District, part also went to Marple.

In 1974, the urban district was abolished and its former area was transferred to Greater Manchester to form part of the Metropolitan Borough of Stockport.

Romiley forms part of the Hazel Grove UK Parliament constituency and the Bredbury Green and Romiley electoral ward in the Metropolitan Borough of Stockport.

There are four primary schools: Romiley Primary School, Bredbury Green Primary School, St. Christopher's Catholic Primary School and Greave Primary School (which is on the border with Woodley).

Secondary education is provided by Werneth School and Harrytown Catholic High School in Bredbury, with much of the suburb being in the catchment area for Marple Hall School in nearby Marple.

Romiley has its own theatre, the Forum Theatre. This is a building owned by Stockport Council but, since 2003, has been managed by NK Theatre Arts, a registered charity which provides all-inclusive performing arts workshops for children, young people and adults. The theatre is also used by many other local community groups in Stockport.

There are many pubs in Romiley, including The Friendship Inn, Romiley Arms, Platform One, Duke of York and Stock Dove.

Romiley's surroundings are rural, although it is a suburb, with fields to the north, south and east. The nearby village of Compstall, sited between Romiley and Marple Bridge, is home to the Etherow Country Park. The park lies at the heart of the Etherow/Goyt Valley; it was one of Britain's first country parks and is one of the most widely visited parks in Stockport.

The suburb is served by Romiley railway station, which is on the Hope Valley Line between Sheffield and Manchester Piccadilly. Services run westbound to Manchester Piccadilly, either via Bredbury or Woodley; eastbound trains travel either to Rose Hill Marple or to Marple and beyond to New Mills Central and Sheffield.

Romiley is served by several bus services, which are operated by Stagecoach Manchester. The most regular services run on a Stockport circular route to Bredbury and Portwood (383 anticlockwise), and to Marple and Offerton (384 clockwise). There is also an hourly 382 service, which runs from Stockport to/from Woodley, via Romiley.

Romiley contains four conservation areas, a designation made by the local council to protect locations which have special architectural or historical character. They help reduce traffic, preserve wildlife and important landscapes; they restrict making changes which affect the look of the area, such as changing front doors, roofing, facades or windows.

The four conservation areas are:

• Barlow Fold (1997, reviewed in 2006) is around 0.5 miles (0.80 km) to the north-east of Romiley village centre and 4 miles (6.4 km) north-east of Stockport. The conservation area covers 0.39 hectares and contains 12 households.
• Chadkirk (2006) is a quiet rural retreat lying approximately 0.5 miles (0.80 km) south of the centre of Romiley. It comprises farmlands, a 17th-century farmhouse, outbuildings, a Victorian walled garden and the 16th-century Chadkirk Chapel; it forms an oasis of peace and tranquility, surrounded on three sides by ancient woodlands and the River Goyt which flows alongside.
• Church Lane (1996, extended in 2006). This is essentially a late 19th-century railway suburb, overlaying the lanes and fields of a former agricultural area; it developed following the opening of Romiley railway station in 1862; however, it has the form and character of a village or earlier community as the area is focused around the landmark church of St Chad (1864–66).
• Greave Fold (1996, reviewed 2006) is 0.5 miles (0.80 km) north of Romiley village centre and approximately 4 miles (6.4 km) north-east of Stockport. The conservation area covers 2.31 hectares and contains 48 households.

A further conservation area adjoins Romiley at Hatherlow in Bredbury.
