Get Yer Ya-Ya's Out!: The Rolling Stones in Concert is the second live album by the Rolling Stones, released on 4 September 1970 on Decca Records in the UK and on London Records in the US. It was recorded in New York City and Baltimore in November 1969, just before the release of Let It Bleed. It is the first live album to reach number 1 in the UK. It was reported to have been issued in response to the well known bootleg Live'r Than You'll Ever Be. This was also the band's final release under the Decca record label and not under their own label Rolling Stones Records.

The Rolling Stones 1969 American Tour's trek during November into December, with Terry Reid, B.B. King (replaced on some dates by Chuck Berry) and Ike and Tina Turner as supporting acts, played to packed houses. The tour was the first for Mick Taylor with the Stones, having replaced Brian Jones shortly before Jones's death in July; this was also the first album where he appeared fully and prominently, having only played on two songs on Let It Bleed. It was also the last tour to feature just the Stones – the band proper, along with co-founder, road manager and session/touring pianist Ian Stewart – without additional backing musicians.

The performances captured for this release were recorded on 27 November 1969 (one show) and 28 November 1969 (two shows) at New York City's Madison Square Garden, except for "Love in Vain", recorded in Baltimore on 26 November 1969. Overdubbing sessions were undertaken during January 1970 in London's Olympic Studios. The finished product featured an overdubbed lead vocal on all tracks except for "Love In Vain" and "Midnight Rambler," added back-up vocals on three tracks, and overdubbed guitar on two songs ("Little Queenie" and "Stray Cat Blues"). However, this album is widely recognized as one of few actual 'live' albums during this era.

The title Get Yer Ya-Ya's Out! is taken from a Blind Boy Fuller song, "Get Your Yas Yas Out". The lyric in Fuller's song was "Now you got to leave my house this morning, don't I'll throw your yas yas out o' door". In the context of Fuller's original song and its use in other blues music, "yas yas" appears as a folksy euphemism for "ass". However, Charlie Watts' T-shirt worn on the album's front cover shows a picture of a woman's breasts, suggesting an alternative explanation. Watts said that his wardrobe on the album cover was his usual stage clothing, along with Jagger's striped hat.
