"You Think You Know Somebody" is a song recorded by American singer-songwriter Hunter Hayes for his second studio album, Storyline (2014). Written by Hayes and Sam Ellis, it has been described by the former as one of the most personal and "intense" songs he's written. It was released to digital retailers April 22, 2014 as a promotional single instantly granted to fans who pre-ordered the album. It entered the Billboard Hot Country Songs at number 34 based primarily on digital downloads.

Critical reception
Markos Papadatos at Digital Journal labelled the song a "spitfire" and praised Hayes for showing off a "dark[er]" aspect to his craft. Glenn Gamboa of Newsday felt the song lacked the "emotional punch" of preceding tracks "Flashlight" and "Invisible", but admitted that it was a "well-crafted... guitar-fueled, brokenhearted rant [that] will fare well on country radio." Listing it as one of four "key tracks" from the album, Billy Dukes at Taste of Country called "You Think You Know Somebody" a "great song" and compared it favorably to the work of Keith Urban. Andrew Unterberger at Spin ranked the song 33rd on the magazine's Top 40 Best Country Songs of 2014 list. He praised Hayes's interpretive abilities, noting that he sounds "more incredulous than heartbroken," and deemed it the album's highlight.

Commercial reception
"You Think You Know Somebody" sold 24,000 digital units in its first week of release and debuted at number 16 on the Billboard Country Digital Songs chart. Due to this strong sales week, the song spent one week on the Billboard Hot Country Songs chart at number 34. As of May 8, 2014, the song has sold 34,000 units.

Music video
In conjunction with the song's digital release, Hayes uploaded a "tour rehearsal session" video to his official YouTube channel on April 22, 2014 that features him performing the song live at the Bridgestone Arena in Nashville, TN. Billy Dukes at Taste of Country described the performance as "passionate" while also expressing pleasant surprise at Hayes's rock-inspired guitar "shredding".
