The new deal will carry through the 2022 season for the 78-year-old Snyder, who will be entering his 27th season with the Wildcats.
"It has been a pleasure watching our football program up close over the past year and seeing one of the greatest coaches in the history of college football continue to positively impact student-athletes while also producing winning seasons on a yearly basis," said Kansas State athletic director Gene Taylor.
"With this new contract, we felt that it was important to recognize his commitment to our football program, and we look forward to his continued leadership."
Snyder, in his second stint with the Wildcats, led the team to an 8-5 record last season, which was capped by a 35-17 victory over UCLA in the Cactus Bowl.
It was the eighth consecutive bowl appearance for Kansas State under Snyder, who is 210-110-1 at the school.
Snyder will earn $3.45 million for the upcoming season and will receive $300,000 raises in both 2019 and 2020.
