"Feeling This" is a song recorded by American rock band Blink-182 for their eponymously titled fifth studio album (2003). The song was released as the lead single from Blink-182 on October 2, 2003 through Geffen Records. It was written by guitarist Tom DeLonge, bassist Mark Hoppus, and drummer Travis Barker, and was produced and mixed by Jerry Finn. The song originated on the first day of producing the album. Its lyrics are purely sexual in nature; the band attempted to juxtapose lust and passion between verses and choruses, thematically connected with a wistful, regretful tone.

The song's composition contains elements of spoken word in the verses and a Latin-inspired back beat in the chorus, and the song ends in a melodic, harmonized duet split between DeLonge and Hoppus. Elements of the song were inspired by rock groups Led Zeppelin and the Beach Boys. The song's music video, photographed by David LaChapelle, depicts a dystopian correctional facility that is overtaken by its inmates. An early version of the song, erroneously titled "Action", was released on the soundtrack for the video game Madden NFL 2004.

"Feeling This" received critical acclaim and the song peaked to number two on Billboard's Modern Rock Tracks chart in late 2003. It was also a top 20 hit in the United Kingdom and Australia. The digital single was certified gold by the Recording Industry Association of America in 2005. Blink-182 has performed "Feeling This" in a number of live appearances, including on Jimmy Kimmel Live!.
