Sir John Philipps, 6th Baronet, PC (c. 1701 – 22 June 1764) was a Welsh politician and lawyer who served as Lord Lieutenant of Haverfordwest from 1761 to 1764.
He gave up the Carmarthenshire seat in 1747, but re-entered Parliament as MP for Petersfield (1754–1761), and Pembrokeshire (1761–1764).
Proposed by his elder brother, he was elected a Fellow of the Royal Society in 1742.
Among the family's servants was Cesar Picton, a former slave from Senegal, who later became a successful coal merchant in Kingston upon Thames, Surrey.
