The OBD-II port in a 2003 Renault Clio is typically located under the dashboard on the driver's side. You can find it near the steering column, often just above the pedals. It may be necessary to remove a small cover or panel to access the port. If you're having trouble locating it, consulting the vehicle's manual can provide additional guidance.
