Sir John Ramsden, 4th Baronet (1755 – 15 July 1839) was an English landowner and Member of Parliament.^[1]

He was born in 1755 and was the only son of Margaret (née Norton) Bright and Sir John Ramsden, 3rd Baronet of Byram, near Pontefract, Yorkshire, whom he succeeded in 1769, inheriting the Manor of Huddersfield and the associated Ramsden Estate. His mother, the daughter of William Norton, Esq. of Sawley, was the widow of Thomas Liddell Bright.^[2]

An Act of Parliament (14 Geo. 3. c. 13) obtained on 9 March 1774, enabled "Sir John Ramsden, Baronet, to make and maintain a navigable Canal from the River Calder, between a Bridge called Cooper's Bridge, and the Mouth of the River Colne to the King's Mill, near the town of Huddersfleld, in the West Riding of the county of York". Completed in 1776 and originally named Sir John Ramsden's Canal, it is now known as the Huddersfield Broad Canal.^[3]

He was elected Member of Parliament (MP) for Grampound under the patronage of Lord Rockingham in 1780, retiring from politics in 1784. He was made High Sheriff of Yorkshire for 1797–98.
