"Fly By II" is a song by English boy band Blue.

It was released on 18 March 2002 as the fourth single from their debut studio album, All Rise (2001).

"Fly By II" is a remixed version of the All Rise album track "Fly By", which samples the song "Rise" by Herb Alpert, while the remix samples from the Notorious B.I.G.

The video for "Fly by II" features Blue in a 2001 BMW X5 (E53) 4.4i, driving to an underground hangout, where the patrons partake in breakdancing, dominoes and rap battling.

The members of Blue then proceed to go upstairs to a rave club, where they dance while performing.
