"How High" is a song by American hip hop duo Method Man & Redman, released as a single on August 15, 1995. It was originally featured on the soundtrack to the 1995 hip hop documentary film, The Show, and has since appeared on several compilation albums such as The Hip Hop Box and Def Jam's Greatest Hits, among several others. The song, produced by Erick Sermon, is the first official collaboration from longtime friends and East Coast rappers Method Man of Wu-Tang Clan and Redman of Def Squad, marking their debut as a duo. The song performed exceptionally well commercially, reaching number 13 on the US Billboard Hot 100 chart. The single has since been certified gold by the Recording Industry Association of America (RIAA).

Redman's vocals on the third verse was sampled on American electro house DJ Armand Van Helden's 1996 single, "The Funk Phenomena". The song was later sampled on Guilty Simpson's "Yikes!".

The duo later remixed the song and included it on their collaborative debut album Blackout! (1999), as well as the soundtrack to their 2001 film, How High. The "How High (Remix)", has a stripped down sound and contains samples from "Fly Robin Fly", as performed by Silver Convention and "I Am Woman", as performed by The Cover Girls.
