John Sparke (c. 1574 – 1640) of The Friary, in the parish of St Jude, Plymouth, Devon, was an English politician who sat in the House of Commons from 1628 to 1629.
Sparke was the son of John Sparke (died 1603) of Plymouth, Devon, Mayor of Plymouth in 1583 and 1591, by his wife Juliana Cock (died 1583), daughter of Gregory Cock, mayor of Plymouth. In the 1580s John Sparke (died 1603) acquired the former Whitefriars Priory in the parish of St Jude, Plymouth (dissolved a few decades before during the Dissolution of the Monasteries), which he made his residence.
He matriculated at Exeter College, Oxford on 13 December 1622, aged 19. He was a student of Lincoln's Inn in 1623. In 1628, probably due to the influence of his wife's family the Rashleighs, he was elected Member of Parliament for Mitchell and sat until 1629 when King Charles decided to rule without parliament for eleven years.
The Sparke family's residence in Plymouth was the former Whitefriars Abbey, in the parish of St Jude, which after the Dissolution of the Monasteries was probably acquired by Giles and Gregory Iselham, who obtained possession of other ecclesiastical property in Plymouth. It was then acquired by the Sparke family, who made it their residence. From Sparke it passed to the Molesworths and Clarkes to the Beweses. The buildings were converted into a hospital for soldiers in the year 1794, when a deadly sickness was ravaging the troops detained at the port for the West India expedition. They were subsequently used as an infirmary for the troops stationed at Millbay and Frankfort Barracks. Parts were used as dwellings, but Friary Court was thenceforth never considered a fashionable address. By 1890 all had disappeared and the bulk of the site was occupied by the Friary Railway Station, now closed, of the London and South Western Railway, with another part occupied by the Roman Catholic Church of the Holy Cross.
In 1620 he married Deborah Rashleigh (1581–1638), a daughter of John Rashleigh (1554–1624), of Menabilly, near Fowey, in Cornwall, builder of the first mansion house at Menabilly, a shipping-merchant, MP for Fowey in 1588 and 1597, and High Sheriff of Cornwall in 1608. By his wife he had children including:
