Coarse facial features (coarse facies) is a constellation of facial features that are present in many inborn errors of metabolism.

| A 16 year old with Mucopolysaccharidosis showing coarse facial features. | |
| Specialty | Medical genetics |
Features include:
- large, bulging head
- prominent scalp veins
- "saddle-like, flat bridged nose with broad, fleshy tip"
- large lips and tongue
- small, widely spaced and/or malformed teeth
- hypertrophic alveolar ridges and/or gums
The head tends to be longer than normal from front to back, with a bulging forehead. This is because of the premature fusion of skull bones in the affected person.
