"Didn't You Know How Much I Loved You" is a song written by Chris Lindsey, Aimee Mayo and Troy Verges, and recorded by American country music artist Kellie Pickler.

An accompanying music video for the song, directed by Roman White, was shot in the Dominican Republic.

"Didn't You Know How Much I Loved You" is a power ballad, backed primarily by piano and electric guitar.

He also complimented her vocals: "Pickler hits the song’s melodic peak she’s soaring, squeezing out every bit of power and emotion her voice can muster.

"[2] Roughstock reviewer Bobby Peacock also described the verses as "pedestrian" but added, "[w]ith a good enough vocal performance, even a trite lyric can be elevated greatly."

"There’s such an incongruity between the softly sung verses and the bombastic chorus that it’s hard to get a handle on how she’s asking the titular question.

[7] Skylar Laine performed the song on the eleventh season of American Idol during the Top 7 week.
