Gilmour's first marriage was to American-born model and artist Virginia "Ginger" Hasenbein, on 7 July 1975.
The couple had four children: Alice (born 1976), Clare (born 1979), Sara (born 1983) and Matthew (born 1986).
They originally attended a Waldorf School, but Gilmour called their education there "horrific".
In 1994, he married novelist, lyricist and journalist Polly Samson.
His best man was his teenage friend and Pink Floyd album artwork designer Storm Thorgerson.
The couple have four children: Gilmour's adopted son Charlie (born 1989 to Samson and Heathcote Williams), Joe (born 1995), Gabriel (born 1997) and Romany (born 2002).
Charlie's voice can be heard on the telephone to Steve O'Rourke at the end of "High Hopes" from The Division Bell.
Gabriel performed piano on the song "In Any Tongue" on the 2015 album Rattle That Lock, making his recording debut.

Gilmour lives with his family on a farm near Wisborough Green, Sussex, and also has a home at Hove.
He also spends time at his recording studio houseboat Astoria near Hampton Court.

Gilmour is an experienced pilot and aviation enthusiast.
Under the aegis of his company, Intrepid Aviation, he amassed a collection of historical aircraft.
He later decided to sell the company, which he had started as a hobby, feeling that it was becoming too commercial for him to handle.
In a BBC interview, he stated:
Intrepid Aviation was a way for me to make my hobby pay for itself a little bit, but gradually over a few years Intrepid Aviation became a business because you have to be businesslike about it.
Suddenly I found instead of it being a hobby and me enjoying myself, it was a business and so I sold it.
I don't have Intrepid Aviation any more.
I just have a nice old biplane that I pop up, wander around the skies in sometimes...
Gilmour does not believe in an afterlife and is an atheist.
He has stated that he is left-wing.
He said that his parents were "Proper Manchester Guardian readers ... Some of their friends went on the Aldermaston Marches.
Mine never did to my knowledge, but they were both committed to voting for the Labour Party."
He described himself as a socialist, "even if I can't quite stick with party politics".
In August 2014, Gilmour was one of 200 public figures who were signatories to a letter to The Guardian expressing their hope that Scotland would vote to remain part of the United Kingdom in the Scottish independence referendum.
In May 2017, Gilmour endorsed Labour Party leader Jeremy Corbyn in the 2017 UK general election.
He tweeted: "I'm voting Labour because I believe in social equality."

Gilmour's net worth is £115 million, according to the Sunday Times Rich List 2018.
