"So Cold" is a song by American alternative rock/metal band Breaking Benjamin. It was released in March 2004 as the lead single from their second album, We Are Not Alone. Despite never having reached the number one spot on the Mainstream Rock chart, "So Cold" holds the record for the most weeks spent in the chart with 62 weeks.^[1] The single was certified Platinum by the RIAA on September 15, 2015,^[2] just before the band's debut album Saturate was certified Gold. A reimagined version was released on October 31, 2019 in anticipation for their 2020 album, Aurora.

The movie 28 Days Later was an inspiration while Benjamin Burnley was writing the song.^[3]

In 2020, Burnley told Apple Music,

I was in New York when I wrote that song, around 2003. It was wintertime, so it was really cold and I was totally cut off from the world in this really cool hotel in Manhattan that’s not there anymore. It was a bit of a lonely time; I was by myself, and just doing my best to write this record. I didn't really think it was all that great at first, but I was in a bad place in my mind back then, 16 or 18 years ago. Then it took off and it was a huge, huge success for us. So I’m glad I was in that dark space, because I owe my whole career to it.^[4]

The music video of "So Cold" was directed by Frank Borin. Its story takes place in the 19th century, judging by the style of clothing, and first shows a preacher standing at the edge of a swamp. The scene then shifts to a group of people walking in a forest. One man can be seen carrying a large stone with the Breaking Benjamin Celtic knot on it. The man, who is being punished for infidelity towards his wife, is shackled to the stone throughout the video and struggles to free himself from it. Towards the end, the group of people arrive at the swamp where the preacher stands. The man carrying the stone walks into the swamp and drowns. His wife appears in a black robe while the woman he cheated with wears a white robe. ^{[citation needed]}

Meanwhile, the band is seen throughout the video in another part of the forest performing the song.
