"Glitter" (capitalized as "GLITTER") is a song recorded by Japanese recording girl group Perfume for their third studio album, JPN (2011). It was written, composed, arranged, and produced by Japanese musician and Capsule member Yasutaka Nakata. The song was included as a B-side track for the group’s single, "Spice". Musically, "Glitter" was described as an technopop song, influenced by dance music. Two versions were released; the original composition, and the remix that appeared on the parent album. It has appeared as the theme song for one commercial and television series in Japan.

Upon its release, the track garnered mixed to favourable reviews from music critics. Many critics believed it was better than the A-side single "Spice", both due to its production and commercial appeal. However, some criticized the album mix over the original edit. Due to the song being released digitally and as a B-side to "Spice", it was ruled ineligible to chart on Japan’s Oricon Singles Chart. However, it peaked at number 88 on Billboard's Japan Hot 100 chart. An accompanying music video was shot by Kazuaki Seki; it features the girls performing and dancing to the song in a blue and black room. It was performed on the groups 2011 JPN concert tour.

"Glitter" was written, composed, arranged, and produced by Japanese musician and Capsule member Yasutaka Nakata. Alongside this, it was recorded, mixed, and mastered by him.
