A creditor who is owed a debt by an individual or a company that is not secured by a security interest over the individual's or the company's assets.

In the context of personal and corporate insolvency, unsecured creditors rank lower in priority than secured creditors and may receive a payment from any remaining assets after the debts of secured creditors are paid in full. Unsecured creditors in a corporate insolvency process most commonly include trade creditors (for example, suppliers).
