WPTY (105.3 FM, "Party 105") is a rhythmic contemporary formatted radio station licensed to Calverton–Roanoke, New York, and serving eastern Long Island.

The station signed on the air on March 27, 1998, as WXXP under the leadership of WLIR program director Jeff Levine and operations manager Skyy.

At first, the station sounded similar to New York City's rhythmic AC WKTU in format as they were playing older dance material.

However, as time went on, Party 105's playlist began to add on newer dance music (house music, trance, freestyle), at times being ahead, and began serving the area with a dance direction, which would prove popular with listeners and gave them an alternative to similarly formatted WKTU, which is also heard in the area.

The on-air staff was fired and the new format ran with limited commercials, with each programming hour sponsored by an individual advertiser.

On December 26, 2006, BusinessTalkRadio.net President and Chief Executive Officer Michael Metter announced the purchases of WLIR, WBON, and WDRE for an undisclosed price[6] but the transaction was never completed.
