"San Francisco (Be Sure to Wear Flowers in Your Hair)" is an American pop^[1] song, written by John Phillips, and sung by Scott McKenzie.^[4] It was produced and released in May 1967 by Phillips and Lou Adler, who used it to promote their Monterey International Pop Music Festival held in June of that year.^[5]

John Phillips played guitar on the recording and session musician Gary L. Coleman played orchestra bells and chimes. Bass guitar was supplied by session musician Joe Osborn. Hal Blaine played drums. The song reached the fourth position on the US charts and the number one spot on the UK charts. In Ireland, it was number one for one week, in New Zealand the song spent five weeks at number one, and in Germany it was six weeks at number one.

McKenzie's version has been called "the unofficial anthem of the counterculture movement of the 1960s, including the Hippie, Anti-Vietnam War and Flower power movements." The song has also been widely regarded as a defining song of the Summer of Love along with the Beatles' "All You Need Is Love".

According to Paul Ingles of NPR, "...local authorities in Monterey were starting to get cold feet over the prospect of their town being overrun by hippies. To smooth things over, Phillips wrote a song, "San Francisco (Be Sure To Wear Flowers In Your Hair)."^[6] Phillips reported writing the song in about 20 minutes.^[7]

The song is credited with bringing thousands of young people to San Francisco during the late 1960s.^{[citation needed][8]}

Different issues of the recording use slightly different titles, including: "San Francisco (Be Sure to Wear Flowers in Your Hair)"; "San Francisco (Be Sure to Wear Some Flowers in Your Hair)"; and "San Francisco 'Wear Some Flowers In Your Hair'".^[9]

Released on May 13, 1967, the song was an instant hit. By the week ending July 1, 1967, it reached the number four spot on the Billboard Hot 100 in the US, where it remained for four consecutive weeks.^[10] Meanwhile, the song rose to number one in the UK Singles Chart,^[3] and most of Europe. In July 1967, McKenzie's previous record label, Capitol, claimed that the "follow-up" to this was their re-release of his earlier single, "Look in Your Eyes."^[11] The single is said to have sold over seven million copies worldwide.^[12]

The song has been featured in several films, including Frantic, The Rock, and Forrest Gump. It was also played occasionally by Led Zeppelin as part of the improvised section in the middle of "Dazed and Confused".^[13][14] U2's Bono also led the audience in a sing-along during their PopMart performances in the San Francisco Bay Area on June 18 and 19, 1997. New Order covered it on July 11, 2014, at the Bill Graham Civic Auditorium in San Francisco.^[15] A cover by Michael Marshall appears in the 2019 film The Last Black Man in San Francisco.^[16]

French singer Johnny Hallyday recorded the song in French, with the title "San Francisco". His version reached number five in Wallonia (French Belgium) in 1967.^[37]

British band Psykick Holiday did a cover in 2017 to mark the 50th anniversary of the song. It was a double A-side single with Let's Go to San Francisco as the other track. The band also did a Summer of Love EP featuring a French & Spanish version of both songs.

In 2020 and 2022, the English tracks came out on the Compilations' "Femme Fatales of Music" Vol. 1 & 2, credited to Vanessa White Smith, the main vocalist with Psykick Holiday. All releases were on Future Legend Records and made available on iTunes.

American rock band Greta Van Fleet is also known to have covered the song live during their early career. Traces of the song can be heard in their unreleased song called "Written in Gold". This version of the song is very reminiscent to the version heard on The Song Remains the Same (film) by Led Zeppelin, which the band is often compared too in terms of style and influences.
