Sir Robert Long, 1st Baronet

Sir Robert Long, 1st Baronet (c. 1600 – 13 July 1673) of Westminster was an English courtier and administrator who sat in the House of Commons at various times between 1626 and 1673.

He held minor administrative offices in the service of King Charles I of England before the English Civil War.

Clarendon suggested that Long loved money too much and was accused, together with John Colepeper, 1st Baron Colepeper, of improperly retaining prize money and disposing of cloth, sugar and other merchandise for their own benefit, resulting from a financially disappointing Royalist naval blockade of the Thames that they had been involved in.

After the Commonwealth forces captured Jersey, where Long had been based for a time, they found a trunkful of compromising correspondence.

It seems he was not trusted by either side, as he subsequently lost his place in the exiled court and had already had his land in England confiscated by Parliament.
