"No More Sad Songs" is a song by British girl group Little Mix from the group's fourth studio album Glory Days (2016). The song was written by Emily Warren, Edvard Førre Erfjord, Henrik Michelsen and Tash Phillips; produced by Electric and Joe Kearns. A remix version, featuring newly-recorded vocals from American rapper Machine Gun Kelly, was released as the third single from the album on 3 March 2017, through Syco Music.

The song was announced as the third single from Glory Days on 1 March 2017.

Digital Spy's writer Lewis Corner stated: "Now that the break-up has well and truly sunk in, the girls are trying to put it behind them by getting back out there and enjoying their lives again. The one request? No more sad songs, obviously. "I'm still trying to put this behind me / I still want to know who's taking you home," Perrie admits on the verse, before it bursts into a spirited electronic-tinged chorus that you can really get swept up in with its addictive squiggles. It's a beautifully defiant twist on a subtle club banger, and Perrie's big vocal run at the end is a real moment."
