"Lips of an Angel" is a song by the American rock band Hinder written by Brian Howes, Austin Winkler and Cody Hanson. It was released as the second single from their album Extreme Behavior. It was their breakthrough hit, charting in the top ten on several Billboard trade charts in the United States, and reaching number one in several countries. It has sold 3.6 million copies in the US as of January 2015, making it one of the most downloaded rock songs.

Jack Ingram released a cover of the song in 2006, which reached No. 16 on the Billboard country music charts.

The lyrics deal with the singer describing his feelings when his favored girlfriend from his past calls late at night, somewhat pleasantly interrupting his current relationship. More than once, a reference to the call being secret is made, and the singer expresses concern of a fight ensuing as a result. The song concludes just as it began, with the singer questioning to why she is calling so late. However, at the end, it is less literal and more figurative, with the underlying meaning of "so late" not at night, but too late in life, perhaps adding an element of sadness to the song, as it ends with the plot unresolved. According to a radio interview done in Atlanta, Georgia the lyrics are loosely based on an actual phone call incident that did happen.

The song experienced the most success in Oceania. On the chart date of February 4, 2007, the song debuted atop Australia's ARIA Singles Chart, replacing Evermore's "Light Surrounding You", keeping the peak position for seven weeks before being replaced by "Straight Lines" by Silverchair. On February 12, it reached the top spot on New Zealand's RIANZ Singles Chart and stayed there for one more week before being dethroned by "This Ain't a Scene, It's an Arms Race" by Fall Out Boy. In the United States, the song reached number one on the Billboard Pop 100 and the Mainstream Top 40 charts in November 2006. Elsewhere, the song had limited chart success, and remains their only hit in most countries it charted in.
