"Where'd You Go" is a song by American hip hop ensemble Fort Minor, the side project of rock band Linkin Park's co-lead vocalist Mike Shinoda. It is the fourth and final single from Fort Minor's debut album The Rising Tied, released on April 14, 2006. The song features Skylar Grey (then known as Holly Brook) and Jonah Matranga. "Where'd You Go" was written and produced by Shinoda. Lyrically, the song is from the perspective of the person left behind in long-distance relationships, and is about the consequences of putting one's career before one's family.
"Where'd You Go" received generally positive reviews from music critics, with most reviewers noting the song's simplicity, as well as praising Brook's vocals. "Where'd You Go" was Fort Minor's most commercially successful single, peaking within the top ten of several international music charts. "Where'd You Go" also peaked at #4 in the Billboard Hot 100 and received a Platinum certification by the RIAA in 2009. A music video for the single was directed by Philip Andelman. The video featured three families, who, according to Shinoda, "share the same sense of loneliness as this song." "Where'd You Go" was included in the set list of numerous Fort Minor concerts.
