The Partridge Family Album is the first of eight studio albums by The Partridge Family. The LP was released in October 1970, a month after the debut of the ABC-TV musical sitcom The Partridge Family starring Shirley Jones and featuring David Cassidy, both of whom feature on the album, as do studio backing vocalists and session musicians. The success of the album – which in early January 1971 reached no. 4 on Billboard's Top LP's chart – was bolstered not only by the hit TV show but by the album's one single release, the massive hit "I Think I Love You", which for three weeks in November and December 1970 topped Billboard's Hot 100 and which NARM declared best-selling single of 1970.
