On Pandora, a radio station is more than a collection of songs. Stations track your tastes as you give thumbs up and down, tailoring the station to fit the aesthetic you want. Deleting a station not only removes the station from your list, but also permanently erases the history of songs you've rated while listening to that station.
Tap the back arrow to back out of the currently playing station. Open the Stations tab if it's not already open.
Swipe from right to left along the station you want to remove.
Tap Delete, and then tap Delete again on the confirmation pop-up.
Deleting a station on the Pandora website takes only a single step. Mouse over the station you want to delete, point to the arrow icon, and then click Delete This Station.
There's no confirmation step; Pandora simply deletes the station as soon as you click the button. If you delete a station by mistake, click Undo on the banner at the top of the screen.
