Gloucester Road is a major highway in Hong Kong. It is one of the few major roads in Hong Kong with service roads. It was named on 14 June 1929 after Prince Henry, Duke of Gloucester, to commemorate his visit to Hong Kong that year. The road is 2.2 kilometres in length and has a speed limit of 70 km/h.

A frontage road is a local road running parallel to a higher-speed, limited-access road. A frontage road is often used to provide access to private driveways, shops, houses, industries or farms. Where parallel high-speed roads are provided as part of a major highway, these are also known as local lanes. Sometimes a similar arrangement is used for city roads; for example, the collector portion of Commonwealth Avenue in Boston, Massachusetts, is known as a carriage road.
