Sir John Shaw, 3rd Baronet (c. 1679–1752) of Greenock was a Scottish Whig politician who sat in the House of Commons between 1708 and 1734.
Shaw did not stand at the 1710 and 1713 general elections, but he continued fight for better regulation of customs in western Scotland.
[2] Shaw celebrated the safe arrival of King George I in October 1714 in an elaborate manner.
[3] With the support of the Duke of Argyll, Shaw revived his parliamentary career, and was returned as a Whig MP for Clackmannanshire in the 1722 general election.
He supported the government and voted for the bills of pains and penalties against those involved in the Atterbury plot.
During the 1745 Jacobite rebellion, he and his wife mobilised support locally for General John Campbell's forces, and raised a militia in Greenock despite threats from the rebels.
