Sir John Meux, 1st Baronet (died February 1657) was an English politician who sat in the House of Commons from 1640 to 1643.
[1] The Meux family was descended from Sir Walter Meux, of Meaux, in France, who married Eleanor Strangways, daughter of Sir Henry Strangways and Margaret Manners (daughter of George Manners, 11th Baron Ros, and Ann St Leger, herself a daughter of Sir Thomas St Leger and Ann, sister of Kings Edward IV and Richard III and their siblings Edmund, Earl of Rutland; Elizabeth of York, Duchess of Suffolk; Margaret, Duchess of Burgundy; and George Plantagenet, 1st Duke of Clarence).
He was re-elected MP for Newtown in the Long Parliament in November 1640 and sat until he was disabled for supporting the King in 1644.
In May 1656, he petitioned Parliament asking to be assessed only on an annuity of £100 since the rest of his property had been "conveyed away for debt and to provide for his children".
[1] Upon the death of his grandson, Sir William Meux, 3rd Baronet, in 1706, the baronetcy became extinct.
