"PPAP (Pen-Pineapple-Apple-Pen)" (Japanese: ペンパイナッポーアッポーペン, Hepburn: Penpainappōappōpen^?) is a single by Pikotaro, a fictional singer-songwriter created and portrayed by Japanese comedian Daimaou Kosaka. It was released as a music video on YouTube on 25 August 2016, and has since become a viral video. As of January 2017^[update], the official video has been viewed over 110 million times, spawned parodies, and has been hailed as the new "Gangnam Style" by various newspapers and online media. The single itself reached number 1 on the Billboard Japan Hot 100 chart and became the shortest single to chart on the Billboard Hot 100. At the end of 2016, the songs charted at number 6 on Japan Hot 100 Year-end Chart.

Kosaka said in an interview that he came up with the song sitting in his house. He was listening to the tune when he picked up a pen to start writing. He thought about his background of being from Japan's biggest apple-producing region (Aomori Prefecture) as he also realized that he had an open can of pineapples on the table.

The song is written in the key of C♯ minor with a common time tempo of 136 beats per minute. Pikotaro's vocals span from F♯₃ to C♯₅ in the song.
