 Enio Chiola of PopMatters.com listed "Who's That Girl" as one of the top-fifteen singles of Madonna's career, stating that it is an "insta-party from the moment in begins".In August 2018, "Billboard" ranked it as the singer's 62nd greatest song; Andrew Unterberger opined that it "expanded on the Spanglish hook and Latin-flavored pop bounce of 'La Isla Bonita' with a similarly contagious chorus and sparkling production from Madonna and Patrick Leonard".Jude Rogers from "The Guardian" felt that "as Balearic moments go, 'La Isla Bonita' was better".
