"Intergalactic" is a song by American hip-hop group the Beastie Boys, released as the first single from their fifth studio album Hello Nasty on May 12, 1998.

The single hit number 28 on the US Billboard Hot 100, making it the band's third Top 40 single there. It also reached number 5 on the UK Singles Chart, where it remains the band's biggest hit in the country.

The song received a Grammy Award for Best Rap Performance by a Duo or Group in 1999.

The song begins with a sample of Stravinsky's ballet Rite of Spring ("The Naming and Honoring of the Chosen One"). The sound effect sample originates from the sound the Resonator makes in the 1986 film From Beyond. Elements of Les Baxter's rendition of Prelude in C# Minor as composed by Rachmaninoff are also used during the verses, and the song also contains elements of the Jazz Crusaders album Powerhouse. Throughout the song, a heavily vocoded voice repeats, "Intergalactic, planetary, planetary, intergalactic; another dimension, another dimension." The closing "Do it!" is sampled from the 1971 Stovall Sisters song "Hang on in There". A shout-out to Mario Cerda, the single's producer, is given in a line from the second verse; "Mario C. likes to keep it clean". On Hello Nasty, a freestyle rap performed by Biz Markie appears directly after the song.

The "Intergalactic" video was made in June 1998. It revolves around a giant robot causing destruction by fighting a giant octopus-headed creature in a city while popping, a parody of Japanese Kaiju films (specifically the series finale of Johnny Sokko and his Flying Robot). Various scenes are filmed in the Shibuya and Shinjuku train stations in Tokyo, Japan in which the band wears the bright uniforms of (Koji) Japanese street construction workers. The video was a regular on Total Request Live and won the award for Best Hip-Hop Video at the 1999 MTV Video Music Awards. They performed "Three MC's and One DJ" and "Intergalactic" at the 1998 MTV Video Music Awards. It was directed by MCA under the pseudonym of Nathanial Hörnblowér.
