Robert John Bagshaw (31 December 1803 – 14 August 1878)[1] was a British Whig politician.
He was born the only son of John Bagshaw, MP for Harwich, who had developed the resort of Dovercourt, near Harwich. Robert continued the development of the town after his father's death in 1861.
After unsuccessfully contesting Great Yarmouth at a by-election in 1848,[2] Bagshaw was elected Whig MP for Harwich at a by-election in 1857—caused by the death of George Drought Warburton—and held the seat until the 1859 general election when he did not seek re-election.[3]
