Sir Edward Turner, 1st Baronet (1691 – 1735) was an 18th-century investor, landowner and baronet.^[1]

He was born in London the son of John Turner, a well-to-do London merchant (d. 1708) and educated at Bicester Grammar School.^[2] Like his father, he became a merchant in London, a Director and sometime Chairman of the East India Company. He served a year as the High Sheriff of Oxfordshire in 1732.

In 1718 he married Mary Page, the daughter of Sir Gregory Page, 1st Baronet, who was a "merchant prince" with great wealth from the British East India Company.^[1] Both Turner and his father-in-law invested in the South Sea Company, but when the company's stock had risen in price in the South Sea Bubble, they sold their shareholdings at a profit before the price crashed in 1720.^[1]

Both men then invested their increased wealth in land. Turner bought two manors in Oxfordshire from Sir Stephen Glynne, 3rd Baronet: one of the manors of Bicester in 1728^[2] and then the manor of Ambrosden in 1729.^[1]

Turner was made 1st Baronet of Ambrosden in 1733.^[3] He died in 1735 and was succeeded by his son Sir Edward Turner, 2nd Baronet.
