Sir Michael Edward Palin (/ˈpeɪlɪn/ PAY-lin; born 5 May 1943) is an English actor, comedian, writer, and television presenter. He was a member of the Monty Python comedy group. He received the BAFTA Fellowship in 2013 and was knighted by Queen Elizabeth II in 2019.

Palin started in television working on programmes including the Ken Dodd Show, The Frost Report, and Do Not Adjust Your Set. He joined Monty Python's Flying Circus (1969–1974) alongside John Cleese, Eric Idle, Terry Gilliam, Terry Jones, and Graham Chapman. He acted in some of the most famous Python sketches, including "Argument Clinic", "Dead Parrot sketch", "The Lumberjack Song", "The Spanish Inquisition", "Bicycle Repair Man", and "The Fish-Slapping Dance". Palin continued to work with Jones away from Python, co-writing Ripping Yarns.

Palin co-wrote and starred in Monty Python and the Holy Grail (1975), Life of Brian (1979) and The Meaning of Life (1983). For his performance in A Fish Called Wanda (1988) he received the BAFTA Award for Best Actor in a Supporting Role. Other notable films include Jabberwocky (1977), Time Bandits (1981), The Missionary (1982), A Private Function (1984), Brazil (1985), Fierce Creatures (1997), and The Death of Stalin (2017).

Since 1980, Palin has made numerous television travel documentaries and is a widely recognised writer and presenter. He has been a travel writer and travel documentarian in programmes broadcast on the BBC. His journeys have taken him across the world, including the North and South Poles, the Sahara, the Himalayas, Eastern Europe, and Brazil; in 2018, he visited North Korea, documenting his visit to the isolated country in a series broadcast on Channel 5. Palin visited Nigeria in 2023 to make a travel documentary that was aired in 2024. From 2009 to 2012 he was president of the Royal Geographical Society.

Palin was born in Ranmoor, Sheffield, the second child and only son of Edward Moreton Palin (1900–1977) and Mary Rachel Lockhart (née Ovey; 1903–1990). His father was a Shrewsbury and Cambridge-educated engineer working for a steel firm. His maternal grandfather, Lieutenant-Colonel Richard Lockhart Ovey, DSO, was High Sheriff of Oxfordshire in 1927.

Palin was educated at Birkdale and Shrewsbury School. His sister Angela was nine years his senior; despite the age gap the two had a close relationship until her suicide in 1987. Palin has ancestral roots in Letterkenny, County Donegal. His great-grandmother fled the Irish Famine and was adopted by a wealthy American family.

When he was five years old, Palin had his first acting experience at Birkdale playing Martha Cratchit in a school performance of A Christmas Carol. At the age of 10, still interested in acting, he made a comedy monologue and read a Shakespeare play to his mother while playing all the parts.

After leaving Shrewsbury in 1962, he went on to read Modern History at Brasenose College, Oxford. With fellow student Robert Hewison he performed and wrote, for the first time, comedy material at a university Christmas party. Terry Jones, also a student at Oxford, saw that performance and began writing with Hewison and Palin. That year Palin joined the Brightside and Carbrook Co-operative Society Players and first gained fame when he won an acting award at a Co-op drama festival. He also performed and wrote in the Oxford Revue (called the Et ceteras) with Jones.
