Sir Alan John Sykes, 1st Baronet (11 April 1868 – 21 May 1950) was an English businessman in the bleaching industry and Conservative politician in Cheshire.
In 1907 Sykes was adopted as the Conservative candidate for Knutsford and a year later gave up the management of the Edgeley Bleachworks, while remaining director of the Bleachers' Association.
Unsatisfied with the political support he was receiving from the local press, in 1912 he gained control of the Stockport Advertiser Group, which was in fact owned by Swain & Co under the direction of an uncle.
In parliament he kept up persistent questioning in support of local interests, and was a leading member of a group of MPs critical of the Government's neglect of Territorial Army and the Volunteer Forces before and during the First World War.
He was unfit for active service in 1914 but served as secretary to the County Committee of the Cheshire Volunteer Regiment and Staff commandant from 1916 until the force's disbandment in 1920.
He remained a confirmed bachelor, with plutocratic tastes - for example yellow Rolls Royces and annual gastronomic tours of France followed by taking the waters at Vichy.
