Chopra is a PunjabiKhatri clan and belongs to the Bara-Ghar (12 House) Khatri section.
The earliest reference to this family name dates back to around 400 AD. One of the important characters of a famous Punjabi legend 'Raja Rasalu' is minister Mahita Chopra. Most scholars agree that Raja Rasalu is a historical figure that ruled from Sialkot and lived sometime between 400 to 500 AD. If this is true, then the Chopra family name developed by that time.
