Critical reception
Upon its release, "Whistle" was met with positive reviews from music critics. Billboard K-Town's Jeff Benjamin opines that Blackpink "[embraces] the hip-hop sensibilities and club-ready sounds with which their seniors gained an international following", referring to their labelmates Psy, Big Bang, and 2NE1. He further stated that the song, "brings together impassioned crooning and their youthful hip-hop delivery with minimal drum 'n' bass and an undeniable whistle hook". Rolling Stone's Brittany Spanos placed Blackpink in her list of "10 New Artists You Need to Know: September 2016", saying: "[a]ll low-end boom and high-end tweets, the infectious 'Whistle' feels like perfect pop update of the similarly chirpy Ying Yang Twins classic 'Whistle While You Twurk'". Entertainment Weekly's Joey Nolfi said that the song "quickly turns up the heat, layering irresistible finger snaps, a saccharine bridge, electric guitar riffs, mammoth bass, and, of course, cow bell-accompanied whistles", and observed that the song would be suitable for American charts.

In a review of the group's discography in May 2019, Rhian Daly of NME asserted that despite the quieter nature of the track, in contrast to most of the group's songs, "it gives the band chance to command things with just their voices – something they do with ease". Following the release of the group's first Korean-language studio album in October 2020, Palmer Haasch of Insider ranked "Whistle" as their third best single overall, stating that: "From Jisoo's opening 'Hey boy,' it's cool and confident, stitched together with a whistle hook and minimalist production elements that allow the members' vocals to shine through." Billboard ranked "Whistle" the 4th best K-pop song of 2016 and the 26th best K-pop song of the 2010s, writing that it "overflows with confidence and made Blackpink's 'girl crush' concept feel impossibly fresh".
