- Charles Spencer Chaplin was born on 16 April 1889 to Hannah Chaplin (born Hannah Harriet Pedlingham Hill) and Charles Chaplin Sr.
- There is no official record of his birth, although Chaplin believed he was born at East Street, Walworth, in South London.
- Grandfather of Dolores Chaplin, Carmen Chaplin, Kiera Chaplin, Oona Chaplin, Aurélia Thiérrée and James Thierrée. Great-uncle of Drunkfux.
- Long after becoming a millionaire, he continued to live in a shabby hotel room, and kept his studio checks in a trunk for months.
- Invented his tramp costume with the help of Roscoe 'Fatty' Arbuckle's pants. Arbuckle's father-in-law's derby, Chester Conklin's cutaway, Ford Sterling's size-14 shoes, the diminutive Charles Avery's jacket, and some crepe paper belonging to Mack Swain (which became the tramp's mustache). The only item that actually belonged to Chaplin was the whangee cane.
- A much-repeated story claims that he once entered a Charlie Chaplin lookalike contest and finished third! In some versions of the story, he came in second.
- On July 6, 1925, he became the first actor to appear on the cover of Time magazine.
- He was also the first actor to have a comic strip about him; Ed Carey's 1916 strip, "Pa's Imported Son-in-Law", detailed the adventures of Chaplin.
- Although Adolf Hitler was not at all a huge fan--in fact, he had been misinformed that Charlie was Jewish, and therefore despised him--he was also well aware of how beloved Charlie was throughout the world at that time, and that was the reason he grew the Chaplin mustache: he thought it would endear him to the people.
- In all his years of living and working in the United States, he never became a citizen.
- As of 2011, he is the only person to receive a 12-minute standing ovation at the Academy Awards when he appeared to accept an honorary award "for the incalculable effect he has had in making motion pictures the art form of this century". It is the longest in the history of the Academy Awards.
- On March 3, 1978, his dead body was stolen from the Corsier-Sur-Vevey cemetery. This took until May 18 when the police found the dead body.
