The four-star guard chose Iowa State over Arizona State and Oregon.
Iowa State head coach Steve Prohm and assistant coach Neill Berry visited Wiggington at Oak Hill Academy in West Virginia on Wednesday.
"Iowa State made me a priority and they always made me feel like family," Wigginton said. "They trust me to be their scoring guard and I trust them to coach me. Coach Prohm is a humble guy. He keeps it real, he doesn't tell you what you want to hear and I like that."
Wigginton made his official visit in September on the same weekend that Iowa State commit Terrence Lewis, ranked No. 59 by ESPN, was on campus. The Iowa State campus made quite an impression.
"When I was on my visit everyone was so genuine the people made me feel like home," said Wigginton
Wigginton, who hails from Halifax, Nova Scotia, played for the Canadian National Team that finished in second place in the U18 FIBA Americas.
"Lindell's mental toughness and competitiveness separates him from so many others." said Canadian team head coach Roy Rana.
Last year, Wigginton also played a prominent role for nationally-acclaimed Oak Hill Academy, winners of the Dick's National tournament. He is a scoring point guard who is terrific in the transition game and is equally effective in the half-court facilitating and scoring.
This is the third commitment for the Cyclones and their second-highest ranked prospect. Four-star guard Darius McNeil and Lewis will step in with Wigginton next year on the perimeter.
In only his second year, Prohm has reeled in a much-needed strong recruiting class. Iowa State will lose a ton of experience, leadership and numbers next year with departures from Monte Morris, Naz Mitrou-Long and Deonte Burton.
