Alfred James Shaughnessy (19 May 1916 – 2 November 2005) was an English scriptwriter, film director and producer best known for being the script editor of Upstairs, Downstairs.

Alfred Shaughnessy was born in London, his father, the Hon Alfred Thomas Shaughnessy, having died while serving with the Canadian army in France two months before. His grandfather Thomas Shaughnessy was an American-born Canadian railway administrator, who was created Baron Shaughnessy in 1916, and his mother was a second cousin of James K. Polk, the 11th US President. He spent his early years living in Tennessee, and in 1920 his mother, Sarah Polk Bradford, married The Hon Sir Piers Legh who then became Equerry to the Prince of Wales, and the family moved to Norfolk Square in London. The family had a butler, cook, footman, two housemaids, a kitchen maid and a lady's maid. The Prince of Wales later visited the house for dinner, and he drew on this when writing the Upstairs, Downstairs episode Guest of Honour. He also often spent weekends and holidays at Lyme Park, his stepfather's ancestral home. Sir Piers Legh later became Master of the Household.
