Williams' agent Michelle Gauvin announced his death on Thursday.
Gauvin did not release any additional information on the cause of the young actor's passing, but said his sudden death comes as a "shock."
"I am not able to hug my parents who lost their only grandchild," she told the outlet. "It's hard."
"Just hearing the devastating news that Logan Williams has passed away suddenly. This picture was early in the filming of The Flash pilot episode back in 2014. I was so impressed by not only Logan’s talent but his professionalism on set," Gustin wrote.
"My thoughts and prayers will be with him and his family during what is I’m sure an unimaginably difficult time for them. Please keep Logan and his family in your thoughts and prayers during what has been a strange and trying time for us all. Sending love to everyone."
Williams has won and been nominated for several acting awards, including multiple Joeys.
In 2015 he won the Joey Award "Best Actor in a TV Drama Recurring Role 8 - 12 Years" for his role as the younger Barry Allen in "The Flash" series.
In addition to "The Flash," Williams also appeared in other television shows, including "When Calls the Heart" and "The Whispers."
