HH Champion (Henry Hyde Champion; January 22, 1859 - April 30, 1928)was a British Christian Socialist social reformer.

In 1888, Champion joined with Annie Besant and her socialist journal, The Link, Catherine Booth and William Booth to help the Matchgirls Union defeat the Bryant & May company (Matchgirls Strike of 1888). He was the first to publish a book by George Bernard Shaw (Cashel Byron's Profession, 1886). In 1889 Champion emerged with Ben Tillett, Tom Mann and John Burns as one of the leaders of the London Dock Strike.

Disillusioned with his colleagues by 1894, he left the Independent Labour Party and emigrated to Australia where he stayed until his death. Like The Bulletin of Sydney, his journal, Champion, published from Melbourne, was a significant influence on culture and radical politics of the time.

His obituary in The Times of May 2, 1928, said: "Champion was an exceedingly able writer and the wielder of a caustic pen. He had, however, the temperament of an aristocrat and an inborn sympathy with Conservative traditions, both of which prevented him from really understanding and sympathizing with the minds of the masses whom he endeavoured to lead."
