Frankby (locally /ˈfræŋkbi/) is a village and former civil parish, in the Wirral district, in Merseyside, England.

It is located on the Wirral Peninsula between Greasby and Newton on the outskirts of the town of West Kirby and south of Hoylake.

Historically within the county of Cheshire, it is part of the Greasby, Frankby and Irby Ward and is in the parliamentary constituency of Wirral West.

[6] The "býr" suffix, included in neighbouring place names such as Greasby, Irby and Pensby, applies to settlements believed to be Viking in origin.

[13] On 1 April 1974, local government reorganisation in England and Wales resulted in most of the Wirral Peninsula, including Frankby, transfer from the county of Cheshire to Merseyside.

Frankby is situated to the north of Thurstaston Hill, with the centre of the village at an elevation of 31 m (102 ft) above sea level.

Named after local landowner Sir Ernest Royden, the park is jointly owned by the National Trust and Wirral Borough Council.

In 1929, the year of the 3rd World Scout Jamboree held at Arrowe Park, the Royden family donated a strip of land to the group (then known as 1st Frankby).
