Sydenham Teast (1755–1813) was a Quaker merchant, fur-trader, shipbuilder and shipowner based in Bristol, England, during the 18th and 19th centuries.
Towards the end of the eighteenth century, Teast became a significant figure in Bristol's trade with Africa.
[3] Teast built two drydocks at Wapping on the Avon in 1755, and a further two at Canon's Marsh on the mouth of the River Frome in 1790.
[4] On 9 September 1782, the company launched HMS Hermione, a fifth-rate 32-gun frigate, the only warship the yard ever built.
Teast's Docks lasted until 1832 at Canon's Marsh, and 1841 at Wapping, where the housing and flats of Merchant's Wharf now occupy the site.
