Harold the Helicopter is a character in the Railway Series books by Rev. W. & Christopher Awdry and the TV show Thomas the Tank Engine & Friends. He is a helicopter who speaks in a manner reminiscent of an RAF pilot as depicted in movies of the 1940s and 50s, using terms such as "wizard" in conversation. He is very proud of being able to fly, and the speed and versatility this gives him. This has led to rivalries with the engines, most notably a race with Percy in his first appearance. Despite this, he is a friend to the railway and has often been able to help the engines out, even though they do sometimes refer to him as "whirlybird".
He is owned by the Coastguard on Sodor, and lives at Dryaw airfield by Thomas' branch line. He keeps a watchful eye over the island in case of trouble, and speeds to the rescue of anyone in distress.
