RNLB Cecil Paine is a retired Liverpool-class non-self-righting lifeboat of the Royal National Lifeboat Institution. It was the second motor lifeboat to be stationed in the English coastal town of Wells-next-the-Sea in the county of Norfolk in the United Kingdom, and was on station at Wells from 25 July 1945 until she was sold in June 1965.

The Liverpool-class motorised lifeboat was a non-self-righting boat operated by the Royal National Lifeboat Institution (RNLI) from its stations around the coast of the United Kingdom and Ireland. The boats were designed for carriage launching and were developed from the Liverpool-Class Pulling and Sailing type of lifeboats - there were two types built, single and twin engined.
