Samuel Ervin Beam (born July 26, 1974), better known by his stage name Iron & Wine, is an American singer-songwriter. He has released eight studio albums, several EPs and singles, as well as a few download-only releases, which include a live album (a recording of his 2005 Bonnaroo performance). He occasionally tours with a full band.

The name Iron & Wine is taken from a dietary supplement named "Beef, Iron & Wine" that he found in a general store while shooting a film.

Beam was raised in Chapin, South Carolina, where his father worked in land management and his mother was a schoolteacher. When he was a child, his family took regular trips to the country, where his grandfather ran a farm. He attended Seven Oaks Elementary School and Chapin High School. While home from college, he was a waiter at California Dreaming restaurant in Columbia. Beam earned a bachelor's degree in art from Virginia Commonwealth University in Richmond, Virginia. He specialized in painting before graduating from the Florida State University Film School with an MFA degree. Before the release of the first Iron & Wine album, Beam's main source of income was as a professor of film and cinematography at the University of Miami and Miami International University of Art & Design.

He had been writing songs for over seven years before a friend lent him a four-track recorder. One of Beam's home recordings came to the attention of Ben Bridwell, of Band of Horses, and eventually to Mike McGonigal, editor of Yeti magazine. McGonigal chose the song "Dead Man's Will", later released on In the Reins, for inclusion on one of his magazine's compilation CDs. Jonathan Poneman of Sub Pop records contacted Beam to propose a deal.

Beam released his first Iron & Wine album, The Creek Drank the Cradle, on the Sub Pop label in 2002. Beam wrote, performed, recorded and produced the album in his home studio. Featuring acoustic guitars, banjo, and slide guitar, the album's music has been compared to that of Nick Drake, Simon and Garfunkel, Elliott Smith, Neil Young and John Fahey.

Also in 2002, Beam recorded a cover of The Postal Service's then-unreleased song "Such Great Heights". Rather than being included on an Iron & Wine release, the track was initially included as a b-side of the original version by The Postal Service. It was later included on the B-sides and rarities album, Around the Well. He then followed up on his debut album in 2003 with The Sea & The Rhythm, an EP containing other home-recorded tracks with a similar style to the songs on the debut.

Beam's second full-length album, Our Endless Numbered Days (2004), was recorded in a professional studio with a significant increase in fidelity. Produced in Chicago by Brian Deck, the focus was still on acoustic material, but the inclusion of other band members gave rise to a slightly different sound. That same year, he recorded the song "The Trapeze Swinger" for the film In Good Company, and had his version of "Such Great Heights" featured in an advertisement for M&M's and in the film and soundtrack for Garden State. This version was later used in a 2006 Ask.com advertisement, and eventually released as a single in 2006 backed with recordings of "The Trapeze Swinger" and "Naked as We Came" made for Radio Vienna.

In February 2005, he released an EP entitled Woman King, which expanded on the sounds of his previous LP with the addition of electric guitars. Each track features a spiritual female figure, and had Biblical overtones.
