I/O is the third studio album by the Canadian rock band Limblifter, originally released on September 28, 2004. The album has recently been reissued on vinyl.

I/O marked a new chapter for the band, with frontman Ryan Dahle reassembling the lineup after the departure of founding members.

The album was praised for balancing polished pop craft with an undercurrent of alternative rock and offbeat lyricism.

It features contributions from Matthew Good and Todd Kerns.

The recent vinyl reissue is the final Limblifter album to be remastered for vinyl by the independent label We Are Busy Bodies.
