Williams Way is a tunnel through the eastern part of the Rock of Gibraltar.

It is one of two tunnels in Gibraltar named after Lt Col A R O Williams, of 178 Tunnelling Company, Royal Engineers. Arthur Robert Owen Williams (1905-1989) was known as "ARO". He had trained as a miner in South Africa and was in charge of tunnelling operation in Gibraltar during World War II. When he left the army he was also given an OBE. Williams also gave his name to Arow Street which is a tunnel entirely inside the rock.
