"Guardian" is a song by Canadian-American recording artist Alanis Morissette, released as the lead single from her eighth studio album, Havoc and Bright Lights (2012). The song was written by Morissette and Guy Sigsworth, and produced by Sigsworth and Joe Chiccarelli. It is a rock song, where Morissette promises to look after a special someone.

The song received positive reviews from music critics, with most of them praising her return and commending its freshness and brightness. The music video was released on July 27, 2012 and it shows Morissette singing on a Berlin rooftop equipped with a set of angel wings and eventually brightens the children and parents she is watching over.

The song was a moderate success in some countries, peaking inside the top 20 on the Austrian and Switzerland charts, while reaching number 41 on the Canadian Hot 100 chart and charting on the Billboard's Adult Pop Songs chart. Morissette has promoted the track with live performances, including Dancing with the Stars, The Ellen DeGeneres Show and The View.

After finishing promotion for Flavors of Entanglement and leaving Maverick Records, Morissette got married and gave birth to a son in 2010. She didn't give information about writing an album, however she was seen leaving Sunset Sound Recorders in Los Angeles (meanwhile the company listed her as a 2011 client). Finally, in November 2011, Morissette appeared at American Music Awards, where she said she had written 31 songs and would release an album the next summer.

It wasn't until May 1 that Morissette announced through Facebook she would be making a few big announcements over the next days. The following day Billboard magazine reported Morissette would release her next studio album, Havoc and Bright Lights, on August 28, 2012. Billboard also revealed the title of the album's lead single.
