"I Need You" is a song written by Dennis Matkosky and Ty Lacy and recorded by American country pop artist LeAnn Rimes.

[4][5] The song spent 25 weeks on the US Billboard Hot 100 and peaked at number 11, and it was also successful outside the US, reaching the top 20 in Canada, Denmark, Finland, Ireland, Spain, Sweden, and the United Kingdom.

[8] It was written by Dennis Matkosky and Ty Lacy,[3] and is in the key of G major with Rimes' vocals spanning two octaves, from E3 to D5.

[16] Entertainment Weekly music critic David Browne gave "I Need You" a "C+" grade and wrote, "This schlock-deluxe ballad finds Rimes in full-diva mode, swooning and growling like a Celine Dion impersonator on Your Big Break.

"[17] According to Carson James, Curb VP of Promotion, "I Need You" was used as the "primary vehicle for pre-promotion" of the "Jesus" mini-series (Country Corner, 2000) that aired on CBS in May 2000 and was the lead track featured on the album.

[18] A review by Billboard stated, "Not since her pop breakthrough "How Do I Live" almost three years ago has [LeAnn] Rimes brought forth a song so naturally beautiful and well-suited to her rich, enveloping vocal style.

[24][25][26][27] The music video for the song features Rimes singing solo in a minimally furnished, abandoned house.
