The 22-year-old French superstar, who has sparked the San Antonio Spurs into the Western Conference finals against Gilgeous-Alexander and Oklahoma City, received 99 of 100 possible first-team votes by a global media panel, and one second-team nod.
They were joined on the elite first lineup by Luka Doncic with 91 first-place votes, who, like Jokic, made his sixth All-NBA first team, and Detroit's Cade Cunningham, who had 60 first-team votes.
Wemby was recently named the unanimous NBA Defensive Player of the Year.
Canada's Gilgeous-Alexander won his second consecutive NBA Most Valuable Player award this season, while Jokic became just the second player ever, joining Larry Bird, to be top-two in MVP voting for six straight seasons.
SGA and Jokic received 100 votes and 500 total points, with Wemby third overall on 498.
The All-NBA second team included Jaylen Brown, Kawhi Leonard, Donovan Mitchell, Kevin Durant, and Jalen Brunson.
The All-NBA third team included Tyrese Maxey, Jamal Murray, Jalen Johnson, Jalen Duren, and Chet Holmgren.
