Albert Louis Hammond OBE (born 18 May 1944) is a Gibraltarian singer, songwriter and record producer. A prolific songwriter, he also collaborated with other songwriters such as Mike Hazlewood, John Bettis, Hal David, Diane Warren, Holly Knight, Carole Bayer Sager and Roy Orbison.

Hammond wrote commercially successful singles for artists including Celine Dion, Joe Dolan, Aretha Franklin, Whitney Houston, Diana Ross, Leo Sayer, Tina Turner, Glen Campbell, Julio Iglesias, Willie Nelson, Lynn Anderson and Bonnie Tyler, and bands Ace of Base, Air Supply, Blue Mink, Chicago, Heart, Living in a Box, the Carpenters, the Hollies, the Pipkins, Starship, and Westlife.

Notable songs co-written by Hammond include "Make Me an Island" and "You're Such a Good Looking Woman" by Joe Dolan, "Nothing's Gonna Stop Us Now" by Starship, "One Moment in Time" sung by Whitney Houston, "The Air That I Breathe", a hit for the Hollies, "To All the Girls I've Loved Before", a Julio Iglesias/Willie Nelson duet, and "When I Need You" by Leo Sayer. In 2015, he received the British Academy's Ivor Novello Award for Outstanding Song Collection.

Hammond is also a solo singer in his own right. His biggest (and only top 20) US Billboard hit was "It Never Rains in Southern California", #5 in 1972. Other songs of his include "Down by the River", "The Free Electric Band", "I'm a Train", and "When I'm Gone". For a time, he was part of the Family Dogg, a vocal band with whom he had the hit "A Way of Life". He has also produced for a number of other artists.

Hammond was born in London, after his family had been evacuated from Gibraltar during World War II. Shortly after the war, the family returned to Gibraltar where Hammond grew up. In 1960, he started in music with Gibraltarian band The Diamond Boys, which had no real commercial success but played a part in Spain's introduction to pop and rock music. The Diamond Boys performed at the first nightclubs in Madrid to stage modern bands, alongside Spanish rock and roll pioneers such as Miguel Ríos.

In 1966, Hammond co-founded the British vocal band the Family Dogg, reaching number 6 on the UK Singles Chart with "A Way of Life" in 1969, taken from the album of the same name.

Hammond moved to the United States at age 26 in 1970, continuing his professional music career. However, he had his greatest commercial success in mainland Europe. He is known for his successful 1970s singles, released on Columbia subsidiary Mums Records: "Down by the River", "It Never Rains in Southern California", "The Free Electric Band" (his only single to chart in the UK), "Half a Million Miles from Home", "If You Gotta Break Another Heart", "The Peacemaker", "I Don't Wanna Die in an Air Disaster", "I'm a Train" and "99 Miles from L.A."

In 1970, Hammond joined forces with Steve Rowland. Billed as "Steve & Albert", the duo released a single, "Follow the Bouncing Ball" which they heavily promoted, particularly in the UK. They appeared on Top of the Pops and The Basil Brush Show in the UK, but the single failed to chart.
