Misimians are a mountainous indigenous tribe in ancient Georgia.

Along with the Sanigs they are thought of as the ancestors of the modern day Svan people, who constitute a subethnos of the Georgian people.

They border the Apsilae tribe.

According to Agathias Scholasticus, both tribes were subjects of the Lazic king.

Misimians are known for participating in Lazic War.

Etymologically the name "Misimians" corresponds to the Svan self-designation Mushüan.
