A retractable clothesline support and method utilizes a pivotable arm hingedly attached to a housing. The arm having a reel with a line such as a clothesline wound thereon can be unlocked and then unreeled. The line support is particularly useful with an RV or other mobile vehicle while traveling for hanging wet clothes or the like for drying purposes. When not in use the clothesline can be wound on the reel, the reel locked and the arm closed for containment within the housing.
