Edward Somerset, 2nd Marquess of Worcester (9 March 1602 or 9 March 1603 – 3 April 1667), styled Lord Herbert of Raglan from 1628–1644, was an English nobleman involved in royalist politics, and an inventor.

While Earl of Glamorgan, he was sent by Charles I to negotiate a peace treaty and alliance with the leadership of the Catholic Irish Confederacy.
He enjoyed some success, but the agreement quickly broke down.
He then joined the Confederates, and was appointed the commander of their Munster Army.

In 1655 he published The Century of Inventions, detailing more than 100 inventions, including a device that would have been one of the earliest steam engines.
