The French playmaker landed five awards to cap a brilliant individual debut campaign with the Hammers after joining from Marseille last summer.
Payet won the Hammer of the Year, Players' Player of the Season, Goal of the Season, Top Goalscorer and Signing of the Season awards in what was a stunning first season in the Premier League.
"It is a huge honour and a defining moment for me at the club," Payet told the club's official website.
"It recognises the hard work I've put in and I am very happy about it. This is the best award a player can win because it is voted by the fans, but I need to thank my team-mates and the coaching staff."
Other award winners on the night included Michail Antonio, who took out the Best Individual Performance award for his display against Tottenham, while Reece Oxford landed the Young Player of the Season award.
