The contest, which has seen a large number of creative and colourful entries across the town, is being run by the Christmas Festival Committee to help keep up seasonal spirits after this year's event fell victim to the pandemic.
The Town Mayor Austin "Chem" Cheminais, who chairs the festival committee, said: "I estimate well over 50 scarecrows all over Llangollen.
"I know of 40 locations that are on the list above and think there are a lot more out there that I don't know about.
"They all look amazing, people in Llangollen are so creative and imaginative.
"I hope people have fun finding them to see for themselves how fantastic they are."
He added: "Santa and his elves will judge the competition in the week leading up to Christmas, and there are two prizes of £25.
"If anyone wants to help choose the winner they can send a picture of their favourite to email@example.com."
