Ashton won the last of his 44 England caps in February 2019.
The 35-year-old joined Tigers on a short-term contract earlier this season, and his hat-trick against Bristol last month saw him become the Premiership’s all-time top try scorer.
Wigglesworth, meanwhile, will continue in his dual role of player and attack coach.
“It is great to be able to agree new deals with all of these players and have them recommit to Leicester Tigers,” Leicester head coach Steve Borthwick told the club’s official website.
“They have all been a part of these early stages in this journey, and I am sure our supporters are pleased to see these new deals announced.
“We have made great strides in the past 18 months, but still have a lot of growth in us and a lot of hard work ahead, which each of these players is committed to.”
A raft of new signings announced by Leicester for next term include fly-half Jimmy Gopperth from Wasps.
Gopperth heads to Tigers following stints with Newcastle, Leinster and Wasps.
Borthwick added: “Jimmy has shown for a number of years in some of the world’s most competitive and tough environments that he is a world-class player.
“A prolific points-scorer capable of playing in various positions, he not only adds valuable depth to our squad, but an incredible amount of experience and knowledge.
“Jimmy is a proven leader and someone who makes the players around him better. We are excited that he wants to be part of what we are building at Leicester Tigers.”
