A person who looks very similar to another person, often referred to as a double or look-alike.
She met her doppelganger at the party, and they couldn't believe how much they looked alike.
Doppelganger → It is formed from "doppel" (from German, meaning double) and "gänger" (from German, meaning walker or goer). The word describes a double or look-alike of a person, literally meaning a "double walker."
Imagine seeing someone who looks just like you walking around — that's what a doppelganger is, a 'double' ('doppel') 'walker' ('gänger').
