"Full Moon" (Korean: 보름달; RR: Boreumdal) is a song recorded by South Korean singer Sunmi, featuring rapper Lena,^[1] for her first EP Full Moon. Written and produced by Brave Brothers, the song was released on February 17, 2014, by JYP Entertainment as the lead single from the EP.

The song marks JYP Entertainment and Brave Entertainment's first collaboration, as mentioned in the first verse of the song: "The first collaboration of JYP, and Brave Sound, here we come, Sunmi."^[2]

The Korea Herald said that the song "delivers a fresh sound, gladly moving away from the typical musical style found on many recent JYP releases. The groovy brass and guitar riffs alongside sensual drumbeats blend in well with Sunmi's husky vocals. The hypnotic repetition of the chorus, “eh eh eh,” is addictive and adds to the seductive mood of the song."^[3]

The music video, directed by Naive Creative Production,^[4] was released along with the song. As of July 2020, it has over 25.5 million views on YouTube.^[5]
