Custos is the Latin word for guard. It occurs in titles such as
- Custos rotulorum, keeper of the rolls
- Custos (Franciscans)
- Custos (Under-sacristan)
The nominative and accusative plural form custodes is well known from the proverbial phrase Quis custodiet ipsos custodes?, "Who has custody of the custodians?", meaning "Who guards the guards?" or "Who watches the watchmen?".
