Frederick Lewis, Prince of Wales (1 February 1707 – 31 March 1751) was heir apparent to the British throne from 1727 until his death. He was the eldest but estranged son of King George II and Caroline of Ansbach, as well as the father of King George III.

Under the Act of Settlement passed by the English Parliament in 1701, Frederick was high in line of succession to the British throne. He moved to Great Britain following the accession of his father, and was created Prince of Wales. He predeceased his father, however, and upon the latter's death on 25 October 1760, the throne passed to Prince Frederick's eldest son, George III.

Prince Frederick Lewis was born on 1 February 1707 in Hanover, Germany, as Duke Friedrich Ludwig of Brunswick-Lüneburg, to Prince George, son of George, Elector of Hanover, who was also one of Frederick's two godfathers. The Elector was the son of Sophia of Hanover, granddaughter of James VI and I and first cousin and heiress-presumptive to the English Queen Anne. However, Sophia died before Anne at age 83 in June 1714, which elevated the Elector to heir-presumptive; Queen Anne died on 1 August the same year, and Sophia's son became King George I. This made Frederick's father the new Prince of Wales and first-in-line to the British throne and Frederick himself second-in-line. Frederick's other godfather was his grand-uncle Frederick I, King in Prussia and Elector of Brandenburg-Prussia. Frederick was nicknamed "Griff" within the family.

In the year of Anne's death and the coronation of George I, Frederick's parents, George, Prince of Wales (later George II), and Caroline of Ansbach, were called upon to leave Hanover for Great Britain when their eldest son was only seven years old. He was left in the care of his grand-uncle Ernest Augustus, Prince-Bishop of Osnabrück, and did not see his parents again for 14 years.
