''King's Disease III'' was met with widespread acclaim. At
Metacritic, which assigns a normalized rating out of 100 to reviews from professional publications, the album has received an average score of 88 based on eleven reviews, indicating "universal acclaim". Concluding the review for
AllMusic, David Crone wrote that, "The resulting work is at once loose and deeply complex, effortless in its incisiveness yet still dazzling at its peaks. The three bullions on the album's cover say it best: this duo keep on producing gold." Assessing the album for
Clash, Robin Murray declared it, "A fantastically consistent, perpetually illuminating full-length, it shows Nas to retain a hunger and sheer fire that so many of his peers have lost. Recalling former glories while remaining fixed on the future, ''King's Disease III'' underlines the rapper's current creative streak." For
The Daily Telegraph, Thomas Hobbs stated that, "Although ''King's Disease III
might have some tonal missteps, Nas and Hit-Boy should be applauded for bringing warm soul samples back into hip hop culture at a time of such darkness and uncertainty. This is Godfather: Part III'' if
Michael Corleone retired without all the treachery; music about being comfortable with your place and making it to the other side." Writing for
HipHopDX, Eric Diep claimed that, "
KD3 keeps Nas in the relevancy conversation because his voice is still impactful, calling to action when some might say he doesn't need to do this anymore. It's a lesson in purposeful storytelling and aging with grace." Reviewing the album for
NME, Niall Smith claimed that, "With ''King's Disease III'', the New York rapper has put the seal on a strong album trilogy that proves that, three decades in, he's still a force to be reckoned with." In the review for
The Scotsman, Fiona Shepherd described the Nas' work as, "moving with the times, while imparting some of his experience and wisdom – as such, he looks backwards and forwards over a pitch-shifted
Mary J. Blige sample and synth arpeggios on album standout 'Reminisce'." Reviewing the album for
Pitchfork, Paul A. Thompson was more critical of it, declaring that, "The paring down of Nas' verses necessarily makes them feel less improvisatory; he has always been such an exacting writer that little seems to be discovered in the recitation of lyrics themselves, but density brings more opportunity for little bends in inflection and hitches in rhythm. The drabbest moments on
KD3 come when he lapses into mechanical entrepreneur-speak ... doled out with a deliberate hand and no room for flourishes that might undercut or deepen its meaning. Fortunately these are far rarer than on the first two King's Disease volumes—and they're balanced by more charming references." Paul Attard from
Slant Magazine was also slightly indifferent about the album, stating: "By adhering to a creative formula typically associated with many foundational Golden Era classics, ''King's Disease III'' often feels like a spartan exercise in pure technical ability." ==Commercial performance==
