Best-selling album in the USA by a solo artist (female)

Come on Over (1997) by Shania Twain (Canada, b. Eilleen Edwards) has sold 15.58 million copies in the USA, as reported by Billboard magazine on 10 October 2014. In November 2004, the album received its most recent (as of March 2015) multi-platinum certification for US shipments of 20 million units, ranking it eighth equal in terms of all-time shipments in the US market. It has also been reported that the album sold a further 1.99 million copies to members of the now-defunct BMG Music Service, taking its total unofficial US sales to 17.57 million.

Come on Over is the second-biggest-selling album since Nielsen SoundScan began tracking US sales in 1991. Metallica's self-titled set (1991) has sold 16.04 million.

Among albums by solo females, as of 10 October 2014, Alanis Morissette's Jagged Little Pill (14.95 million), Norah Jones' Come Away with Me (11.02 million) and Adele's 21 (11 million) trailed the US sales of Come on Over in the Nielsen SoundScan era (since 1991). The Whitney Houston-dominated original soundtrack album The Bodyguard had sold 12.14 million copies by the same date.

Worldwide, The Bodyguard (1992) has sold an estimated 44 million copies and is the only album (studio or otherwise) credited to a female solo artist (more accurately, Whitney Houston and various artists) with higher sales than Come on Over. The biggest-selling studio album by a solo female after Come on Over is Alanis Morissette's Jagged Little Pill (1995), with estimated worldwide sales of 33 million copies as of March 2015.

Come on Over is the world's biggest-selling country music album (although sales were boosted by a pop-orientated international version, first released in 1998) and the biggest-selling album by a Canadian act, and it was also the world's top seller of the 1990s, shifting 22 million copies in the last 26 months of the decade (since its release on 4 November 1997).

The album spawned an incredible 12 singles, including "Man! I Feel Like a Woman!", "That Don't Impress Me Much", "From this Moment On" and "You're Still the One", the latter becoming a first-dance favourite at wedding receptions.

The Woman in Me (1995) and Up! (2002), with RIAA (Recording Industry Association of America) shipment certifications of 12 million (12x multi-platinum) and 11 million (11x multi-platinum) respectively, have also achieved remarkable US success for Twain.

In a March 2015 interview with Andy Cohen on the US chat show Watch What Happens Live, Twain revealed that she'd earned approximately $20 million (£13.3 million, as of 12 March 2015) from the success of Come on Over.
