"Baby Blue" is a song written by Aaron Barker, and recorded by American country music artist George Strait. It was released in April 1988 as the second single from his album If You Ain't Lovin', You Ain't Livin'. It was a number-one hit in the United States, while it peaked at number 3 in Canada.

The narrator talks about a girl with baby blue eyes who had a profound impact on his life. She was in his life for a short time, but he still thinks of her often, especially when he sees the skies that her eyes matched in color. Though it has never been confirmed, it has long been thought that Strait sang this song for his daughter, Jennifer, who died at 13 in an automobile accident in San Marcos, Texas.

Kevin John Coyne of Country Universe gave the song an A grade, calling it "another one of Strait’s smoothest pop performances, with just enough country touches in the production to keep his traditionalist credentials intact." Coyne states that "taken literally as a love gone wrong song, it’s a beautiful piece of work."
