Dylan Thomas Boathouse is a house in Laugharne, Wales, in which the poet Dylan Thomas lived with his family between 1949 and 1953, the last four years of his life. It was at this house that he wrote many major pieces. It has often been suggested that he wrote Under Milk Wood here but more recent research suggests that fewer than 300 lines of the play were written in Laugharne. The house is set in a cliff overlooking the Taf Estuary.

Dogs can be taken into the garden and onto the terrace, but must be kept on a lead at all times. Guide dogs are allowed in the house. The Boathouse is a 10 minute walk from the centre of Laugharne along Dylans Walk, passing the Writing Shed which can be viewed from the pathway.
