The Melania Trump replacement theory is a conspiracy theory that First Lady of the United States Melania Trump has been replaced, or is sometimes replaced, by a body double, and that the "real" Melania is either dead, has refused to attend occasional events, or has exited from public life entirely. Supporters of the theory allege physical differences in facial features, bodily dimensions, or behavior between the original and supposed 'replacement' Melania, and changes in President Donald Trump's language in referring to Melania.
