A faucet with a rotatable outlet structure includes a main body, a valve assembly disposed in the main body, a connecting structure rotatably received in the main body, an outlet structure rotatably mounted onto the main body and a control lever connected to the valve assembly, wherein the outlet structure includes an outer tube and an inner tube received in the outer tube. The outer tube is engaged to the connecting structure and the inner tube is securely sleeved on the connecting structure. Consequently, the inner tube is rotated with the outer tube when the outer tube is rotated relative to the main body such that inner tube does not need to be twisted when the outer tube is rotated relative to the main body.
