John Egerton, 2nd Earl of Bridgewater, English politician, Lord Lieutenant of Buckinghamshire (died 1686)

John Egerton, 2nd Earl of Bridgewater, PC, was an English nobleman from the Egerton family.

There has been a Lord Lieutenant of Buckinghamshire almost continuously since the position was created by King Henry VIII in 1535. The only exception to this was the English Civil War and English Interregnum between 1643 and 1660 when there was no king to support the Lieutenancy. The following list consists of all known holders of the position: earlier records have been lost and so a complete list is not possible. Since 1702, all Lord Lieutenants have also been Custos Rotulorum of Buckinghamshire.
