Atin Cu Pung Singsing is a traditional Filipino folk song from Central Luzon, Philippines in Kapampangan sung by adults and children. The precise origins of the song are unknown, and there is debate whether it was pre-historic or colonial. Its melody is most likely from the 18th century as it was similar to Spanish and Mexican folk songs of the period. The song has a woman as its main character and a man as a secondary character. The woman in the song was looking for a missing ring given by her mother and offers her love as a prize for the man who could find it.

In popular culture The folk song was interpreted by Filipino popular artists such as Lea Salonga in Ryan Cayabyab's Bahaghari album, Freddie Aguilar and Nora Aunor. It was also performed by different orchestras and brass bands.

The 1985, film Virgin Forest directed by Peque Gallaga, has it sung by adventurers while sailing the Pampanga River.

The popular Filipino children’s song Ako ay May Lobo (literally: "I have a Balloon") borrows the melody of this folk song.

Michael Raymon Pangilinan, a Kapampangan language scholar, presented a paper titled “Atin ku pûng singsing: discussion on the mystical and anti-colonial symbolisms of an ancient Kapampangan song” at the 1st International Conference on Kapampángan Studies held in Angeles City in September 2001. Based on his paper, Atin Ku Pûng Singsing has a deeper meaning hidden in the words of the song, just like any other folk song back in the day.
