A look-alike, or double, is a person who bears a strong physical resemblance to another person, excluding cases like twins and other instances of family resemblance.
Some look-alikes have been notable individuals in their own right, such as the actresses Margot Robbie and Jaime Pressley. Other notable look-alikes have been notable solely for resembling well-known individuals, such as Clifton James, who acted as a double for British Field Marshal Bernard Montgomery during World War II.
Close physical resemblance between individuals is also a common plot point in works of fiction.

According to a paper published in 2022 in the journal Cell Reports, look-alikes share many common genetic variations and are more likely than non-look-alikes to have characteristics in common.
With the advent of social media, there have been several reported cases of people finding their "twin stranger" online. There are several websites where users can upload a photo of themselves and facial recognition software attempts to match them with another user of like appearance. Some of these sites report that they have found numerous living doppelgängers.
Since 2000, photographer François Brunelle has documented look-alikes worldwide.

A popular story about King Umberto I of Italy tells of the king eating in a restaurant and discovering the owner was his dead-ringer double. The story goes that upon talking to the man, Umberto learned of a string of coincidences between their lives, such as: the two men had been born in the same town on the same day, and had both married a woman with the same name, and the restaurant had opened on the day of Umberto's coronation. Umberto's assassination in 1900 is said to have happened the same day that he heard the news that the restaurateur had died in a shooting. This story is cited often in popular culture (Ripley's Believe It or Not!, The Big Book of the Unexplained) and may have been embellished somewhat.
The United Kingdom's King George V (1865–1936) and Russia's Tsar Nicholas II (1868–1918), who were first cousins (their mothers were sisters), bore an uncanny resemblance. Their facial features were distinguishable only up close, particularly their eyes. At George's wedding in 1893, according to The Times of London, the crowd may have mistaken Nicholas for George due to their similar beards and attire.
