Two Against Nature was met with both commercial and critical success. At Metacritic, which assigns a normalized rating out of 100 to reviews from professional critics, the album received an average score of 77, based on 13 reviews, indicating "generally favorable reviews". Writing in March 2000 for The Village Voice, Robert Christgau applauded the music as an excellent "rock comeback" and a "jumpier and snappier, sourer and trickier and less soothing" iteration of the jazz pop featured on Steely Dan's 1977 album Aja, describing it as "postfunk". Thematically, he found it unified by fictitious yet revelatory accounts of "dirty old men" seeking "validation" and "excitement" in their sex lives, which are "full of heady infatuations and random acts of cruelty, self-interest and self-hate, vicious cycles blowing hot and cold", all conveying "the urgency of attraction". Stephen Thomas Erlewine of AllMusic appreciated the "sharp humor" in the lyrics, but was especially impressed by the music's "depth and character", as he observed "nearly endless permutations within their signature sound". A dissenting view came from Pitchfork reviewer Brent DiCrescenzo, who dismissed the songs as "lengthy, indistinguishable" and "glossy bop-pop" while suggesting Steely Dan lack "soul".
At the 2001 Grammy Awards, Two Against Nature earned Steely Dan wins in the categories of Album of the Year, Best Pop Vocal Album, Best Engineered Album – Non-Classical, and Best Pop Performance by a Duo or Group with Vocals (for the single "Cousin Dupree"). For these awards, the band was in competition with younger, more popular recording acts such as NSYNC, Britney Spears, Radiohead, Beck, and Eminem. According to Stereogum writer Zach Schonfeld, Steely Dan's success at the Grammys represented a "revenge of the [baby] boomers" and contributed to resentment among younger listeners toward the band: "[T]he sight of two smug jazz-rock nerds collecting their Grammy from Stevie Wonder as Radiohead and Beck went home nearly empty-handed—helps explain why so many Gen X-ers and old millennials grew up loathing both Steely Dan and the Grammys in equal measure. Needless to say, Steely Dan's elliptical character studies set to yacht rock sleaze didn't speak to disaffected American youth the way, say, The Marshall Mathers LP did."
Steely Dan's supporting tour of North America, Europe, and Japan was equally successful, encouraging them to record the 2003 album Everything Must Go.
