The Mmrnmhrm are a fictional race of aliens from the sci-fi computer game Star Control.

Originally the Mmrnmhrm were an entirely robotic race whose origin was unknown. It was later revealed that a "Mother Ark" mothership had appeared within the vicinity of Procyon, began manufacturing numerous Mmrnmhrm and then either stopped by design or malfunctioned. Physically, the Mmrnmhrm resemble a series of metal disks.

The Mmrnmhrm starship is called the "Transformer", or "X-Form" for short. It is capable of transforming from a slow moving but highly maneuverable form with twin lasers to a faster, considerably less maneuverable form that utilizes twin semi-homing rockets.

After the Alliance of Free Stars lost the war to the Ur-Quan, the Mmrnmhrm began a process by which they merged with the Chenjesu to form the Chmmr. It is believed that no "pure blooded" Mmrnmhrm or Chenjesu existed after this occurred.

All words in the Mmrnmhrm language consists of consonants.
