The Honourable Frederick Threepwood, known as "Freddie", is the second son of Lord Emsworth in the stories and novels of P. G. Wodehouse. At first, Freddie is a rotund and loutish lad, expelled from Eton and Oxford and a failure in the Army. After his father is obliged to pay his £500 gambling debt, he insists on Freddie's taking up residence at Blandings Castle where the father may keep the son out of trouble. However, by Leave it to Psmith, Freddie has lost weight, and he changes his lazy ways upon marrying Aggie Donaldson.

Freddie has one brother, George, Viscount Bosham.
