A lid with a straw for a beverage container is described. The lid includes a supporting structure to house the straw. The lid includes a door structure to close the straw. The door structure is rotatably or pivotally connected to the supporting structure. The lid includes a vent to prevent a vacuum from forming in the interior of the beverage container. The door structure also bends the straw to cover the vent in order to close the vent. The supporting structure positions the straw at an optimal angle towards a user's mouth when the straw is released from the supporting structure by opening the door structure.
