Penelope Ann Valentine (13 February 1943 - 9 January 2003) was a British music journalist, rock critic, and occasional television personality.
She was born in London, of Jewish and Italian ancestry. In 1959 she became a trainee reporter, first on the Uxbridge Post, and in the early 1960s on Boyfriend, a weekly magazine for teen girls. In 1964, she joined the staff of Disc, a weekly pop music magazine (later Disc and Music Echo), as a journalist and record reviewer, becoming for a time Britain's most influential reviewer of new pop singles. According to fellow journalist Richard Williams, "She was probably the first woman to write about pop music as though it really mattered." She loved soul music, and supported singers such as Aretha Franklin and Marvin Gaye before they became famous. As a young woman, she also wrote articles for a variety of publications on the then-current Swinging London phenomenon. Chris Welch commented that she "was part of a social whirl of receptions, parties and night-clubbing that made Swinging London such fun...The Beatles and Rolling Stones certainly preferred to be interviewed by the vivacious young lady from Disc magazine than by some spotty chap in a raincoat." She also made regular appearances on Juke Box Jury in the mid-1960s.
In 1970 she left Disc to join a new magazine, Sounds, and in 1973 was hired by her friend Elton John to become the press officer for his record label, The Rocket Record Company. She also wrote for Record Mirror, and Melody Maker,  and in the 1970s for the American rock magazine Creem. After a period working in New York, she returned to London in 1975 to help launch another new magazine, Street Life, later joining Time Out before leaving in 1980 to help found the more politically radical City Limits. She became active in a number of bodies, including Women in Media and the National Union of Journalists. After gaining a BA in film studies and English, she then pursued a freelance career teaching and writing. With Vicki Wickham, she wrote a biography of Dusty Springfield, Dancing With Demons (2000).
She died at the age of 59 after suffering from cancer for some time.
