Sir Philip Jennings-Clerke, 1st Baronet (c. 1722 – January 1788) was an MP for Totnes, and the 1st Jennings-Clerke Baronet.
He was the son of Philip Jennings of Duddleston Hall, Shropshire, and was baptised Philip Jennings. He married Anne, daughter of Colonel Richard Thompson. He had an "undistinguished military career" in the Horse Guards attaining the rank of Lieutenant-Colonel. He succeeded to the estates of his maternal uncle Sir Talbot Clerke, 6th Baronet, and changed his name to Jennings-Clerke in the early 1760s. Around 1770 he bought a lodge now known as Foxlease, just outside Lyndhurst, Hampshire, and converted it into a grand, two-storey mansion.
He was a Member of Parliament for Totnes between 1768 and 1788. He was created 1st Baronet Jennings-Clerke of Duddlestone Hall on 26 October 1774.
His only remaining son, Sir Charles Philip Jennings survived him by only a few months, whereupon the baronetcy became extinct.
