The Oman Professional League Cup (Arabic: كأس دوري المحترفين عمان) (known as the Mazda Professional Cup for sponsorship reasons), previously known as the Oman Federation Cup, is an Omani football competition.

The competition tends to feature all clubs currently playing in the top flight.

In 2014, ahead of the 2014-15 Oman Professional League Cup, Oman Football Association announced that Mazda had agreed to sponsor the Professional League Cup and would be known as the Mazda Professional Cup for a period of four years.

According to a four-year agreement reached by the two parties, Mazda became the title sponsor of the 14-team competition.
