Katie Herzig (born March 6, 1980) is an American singer-songwriter whose songs have appeared often in movies, TV shows, and commercials.

She was drawn to audio editing after using the computer programs Pro Tools and GarageBand, recording songs on a laptop in her bedroom.

The band broke up in 2006, leaving Herzig free to pursue the solo career she had already begun in 2004 when she released her debut album Watch Them Fall.

She produced the album herself, recorded it at home using Pro Tools, and played most of the instruments: electric and acoustic guitar, banjo, keyboards, and percussion, in addition to her singing and songwriting.

In September 2012, she worked for the campaign "30 Songs/30 Days" to support Half the Sky: Turning Oppression into Opportunity for Women Worldwide, a multi-platform media project inspired by Nicholas Kristof and Sheryl WuDunn's book.
