Harry Freeman (29 July 1858 – 30 July 1922) was an English music hall performer of the Victorian era and early twentieth century, and the first King Rat of the show business charity the Grand Order of Water Rats.

In his early teens he moved to Birmingham where he was mainly to be based as an entertainer until his death.

Freeman became a popular entertainer in the music halls of London and the provinces, but he never gained the fame or success in these that he held in his native Birmingham.

[2] During the early 1890s Freeman was living in London, and when the Grand Order of Water Rats was formed in 1890 by Joe Elvin and Jack Lotto, music hall star Dan Leno was to have been the first King Rat of the order, but he preferred not to be King for the first year, and the office went instead to Freeman.

Harry Freeman died on 30 July 1922 following an abdominal operation in St Peter's Hospital in Covent Garden.
