Small round cell tumours (SRCT), also small round blue cell tumours (SRBCT), are a group of tumours that have a similar histologic appearance.
It is a group of tumours that is seen more often in childhood than adulthood.

- Neuroblastoma.
- Wilms tumour (AKA nephroblastoma).
- Alveolar rhabdomyosarcoma.
- Ewing sarcoma/PNET - this entity is dealt with in the bone tumours article.
