Middle English hirchon, urchon 'hedgehog', from Old Northern French herichon, based on Latin hericius 'hedgehog'.
An urchin was originally a hedgehog, and the name, based on Latin hericius ‘hedgehog’, is still used in some English dialects. People started applying urchin to poor, raggedly dressed children in the mid 16th century, though this did not become common until more than 200 years later. As a name for a marine invertebrate sea urchin comes from the original sense, referring to the spines on its shell.
