George Mitchell Seabroke FRAS[1] (1 April 1848 – 1 April 1918) was an English amateur astronomer.[2] By profession he was a solicitor.[1]

He took an interest in astronomy while a pupil at Rugby School.[3] Together with the school's Mathematics and Science Master, James Wilson (later Canon of Worcester), he observed double stars at the Temple Observatory.[1] He remained at the observatory, carrying out observations and promoting the study of astronomy to the schoolboys of Rugby School.[1] The Observatory boasted an 8¼ inch (210mm) aperture refracting telescope built by Alvan Clark of America.[4]

He was one of the founders of the British Astronomical Association, and served as its Double Star Section Director from 1892 to 1915, its Saturn Section Director from 1899 to 1911, and its national president from 1900 to 1902.[1] He also served as Midland Branch President from 1902 to 1903.
