"Welcome to the Jungle" is a song recorded by British girl group Neon Jungle for their 2014 debut album of the same name. It was released by RCA Records as the album's third single on 18 April 2014. The track was written and produced by French duo SoFly and Nius and American rapper Snob Scrilla, with additional songwriting by Cassie Davis and Yoan Chirescu, and additional production by Baby. "Welcome to the Jungle" was one of the first songs recorded by Neon Jungle and served as the inspiration for their band name. It features a rap by group members Amira McCarthy and Jessica Plummer. It is an uptempo electronic dance music-electropop song with a "club-friendly" urban sound and "faint traces" of dancehall and reggae. Lyrically, the song concerns the subjects of partying, relationships with men, and having a good time. It is one of the official songs of the 2015 Copa América in Chile.

"Welcome to the Jungle" was written and produced by SoFly and Nius and Snob Scrilla, with additional songwriting by Cassie Davis and Yoan Chirescu, and additional production by Baby. It was mixed by James F. Reynolds and mastered by Dick Beetham, while Chirescu was responsible for the track's guitar melody. It was one of the first tracks the group recorded in 2013; both the song and the group were nameless at the time. Upon hearing the demo version of the song, group member Amira McCarthy was shocked that the track was being pitched to Neon Jungle to record, feeling that it should have previously been a hit for a well-known American recording artist. McCarthy originally felt that it was difficult to improve upon the song's demo version, but once the quartet recorded the studio version, said "it is one of those songs that when you hear it you cannot help but get into it, totally". Thematically, the track was developed as one that would "welcome" Neon Jungle's fans to what the group were about. The song featured a rap that was initially intended as a guest slot, but producers were impressed with McCarthy and Jessica Plummer's vocal conviction during its recording and decided to scrap the planned guest slot altogether.
