安德鲁·赫胥黎爵士，OM，FRS（Sir Andrew Fielding Huxley，1917年11月22日－2012年5月30日）出生于英国伦敦，是一位生理学家与生物物理学家，与艾伦·劳埃德·霍奇金共同研究神经的动作电位，两人因此与研究突触的约翰·卡鲁·埃克尔斯共同获得1963年的诺贝尔生理学或医学奖。

赫胥黎在1955年获选成为皇家学会会员，并在1974年获得骑士勋衔。此外，他也是赫胥黎家族的成员之一，父亲是小说家里欧纳德·赫胥黎（Leonard Huxley），祖父是19世纪的著名生物学家汤玛斯·亨利·赫胥黎。

Sir Andrew Fielding Huxley OMPRS (22 November 1917 –30 May 2012) was a Nobel Prize-winning English physiologist and biophysicist. He was born into the prominent Huxley family. After graduating from Westminster School in Central London, from where he won a scholarship to Trinity College, Cambridge, he joined Alan Lloyd Hodgkin to study nerve impulses. Their eventual discovery of the basis for propagation of nerve impulses (called an action potential) earned them the Nobel Prize in Physiology or Medicine in 1963. They made their discovery from the giant axon of the Atlantic squid. Soon after the outbreak of the Second World War, Huxley was recruited by the British Anti-Aircraft Command and later transferred to the Admiralty. After the war he resumed research at The University of Cambridge, where he developed interference microscopy that would be suitable for studying muscle fibres. In 1952 he was joined by a German physiologist Rolf Niedergerke. Together they discovered in 1954 the mechanism of muscle contraction, popularly called the "sliding filament theory", which is the foundation of our modern understanding of muscle mechanics. In 1960 he became head of the Department of Physiology at University College London. He was elected a Fellow of the Royal Society in 1955, and President in 1980. The Royal Society awarded him the Copley Medal in 1973 for his collective contributions to the understanding of nerve impulses and muscle contraction. He was conferred a Knight Bachelor by Queen Elizabeth II in 1974, and was appointed to the Order of Merit in 1983. He was a fellow of Trinity College, Cambridge, until his death.
