The following is a list of people who are known for their dwarfism and who have been open about it. While these people are not known for being the shortest ever, they have been mentioned in sources describing how the condition has affected their lives. Dwarfism is caused by several different types of medical conditions, and is typically defined as an adultA with a height of 147 cm (4 ft 10 in) or less. Records or mentions of people with dwarfism have not always been kept well, resulting in estimated heights that were taken from eyewitnesses. In some given cases the height of the person is unknown except to say that they were mentioned as a "dwarf" in various media. This list does not include every prominent person with dwarfism, as others are already included on other linked Wikipedia lists.
