"Close" is a song recorded by American singer Nick Jonas from his third studio album, Last Year Was Complicated.

The song was written by Tove Lo, Julia Michaels, Justin Tranter, and its producers Mattias "Mattman" Larsson and Robin Fredriksson.

[4] James Grebey of Spin magazine called "Close" a "sultry" track and deeply personal.

Stephen Erlewine of AllMusic wrote a positive review saying "'Close,' a duet with Tove Lo, is perhaps the best showcase for this aspect of Nick Jonas, but the entirety of Last Year Was Complicated walks a fine line between immaculately produced pop confection and personal confession.

[11] Jonas performed the song as a part of his setlist for the Future Now Tour with Demi Lovato singing Lo's lyrics.
