William Ryder (mayor)

Sir William Ryder (died 30 August 1611) was an English merchant and politician who served as the Lord Mayor of London in 1600.

As mayor, he played a prominent role in quashing the abortive rebellion led by the Earl of Essex, by publicly proclaiming Essex a traitor, which immediately caused much of his support to melt away.

He had a son Ferdinando, who predeceased him, and two daughters: Mary, wife of Sir Thomas Lake, Secretary of State, and Susan, third wife of Sir Thomas Caesar, MP and Baron of the Exchequer.

Upon the death of his brother Edward Ryder in 1609, he acquired the manor of Leyton Grange in Essex; this manor had previously been owned by Sir Oliver Cromwell, uncle of the Lord Protector.
