Dominic Christopher Sandbrook (born October 1974) is a British historian, author, columnist, podcaster, and television presenter. He has written many popular history books as well as articles in newspapers, presented history shows on BBC Television and Radio, and since 2020 co-hosts The Rest is History podcast with the historian and author Tom Holland.

Dominic Christopher Sandbrook was born in October 1974 in Bridgnorth, Shropshire. He was educated at Malvern College, then an all-boys independent school in Worcestershire.

He studied history and French at Balliol College, Oxford. He then studied for a Master of Letters (MLitt) degree in history at the University of St Andrews and a Doctor of Philosophy (PhD) degree at Jesus College, Cambridge. His doctoral thesis, "The political career of Senator Eugene McCarthy", was completed in 2002.

Previously a lecturer in history at the University of Sheffield, Sandbrook has been a senior fellow of the Rothermere American Institute at the University of Oxford and a member of its history faculty. He was a visiting professor at King's College London, and a freelance writer and newspaper columnist. In 2007 he was named one of Waterstones' 25 Authors for the Future. In July 2021 he was elected a Fellow of the Royal Historical Society (FRHistS). During his academic career he lectured left-wing activist Owen Jones.

Sandbrook's first book was a biography of the United States presidential candidate Eugene McCarthy.

The historian David Stebenne gave it a mixed review, writing that "Although Sandbrook's book describes McCarthy's life and work with outstanding grace and clarity, using him as a vehicle to explain the odyssey of American liberalism since World War II poses some problems". The historian Doug Rossinow was more positive, writing that "This is a very fine account in many ways, very skillfully written and exhaustively researched. Eugene McCarthy is an excellent and provocative work, one I heartily recommend". Both David Stebenne and Jennifer Delton particularly praised the initial sections of the book on McCarthy's early career and formative influences. Delton wrote that “While the author does a great job of tying the early McCarthy to his historical moment, he is less successful in doing the same with the later McCarthy".

McCarthy himself told journalists that he "liked the early part of the book, which described his early life as a college professor and his early battles in Minnesota Democratic-Farmer-Labor politics" but disliked the later sections. McCarthy said that "What Sandbrook writes about the early years is pretty good, but every page after the first 50 is trash", calling the book "almost libellous".

In 2005 Sandbrook published Never Had It So Good, a history of Britain from the Suez Crisis to the Beatles, 1956–63. It received mixed reviews.
