After being out of coaching for three years, on November 24, 2008, Bill Snyder was named for a second term as head football coach at Kansas State University, beginning in the 2009 season.
He is one of the few coaches to coach in a stadium or arena that is named for him; as previously mentioned, the former KSU Stadium was renamed for him on the day after he announced his original retirement.

In the first season of Snyder's second tenure, the team posted a 6–6 record overall and finished tied for second in the Big 12 North division with a 4–4 conference mark.
In his second season in 2010, the team had a 7–6 record and played in the inaugural Pinstripe Bowl against the Big East's Syracuse University at Yankee Stadium in New York City.

Snyder earned his 150th win with a season opening victory over Eastern Kentucky on September 3, 2011.
During the same season, Snyder became the first FBS coach to have a son (Sean) as an assistant and a grandson (Tate) playing for him at the same time.
Coach Snyder led the 2011 team to a 10–2 record in the regular season, finishing second in the Big 12, and earned a berth in the Cotton Bowl.
The Cotton Bowl was K-State's first "major" bowl since the 2004 Fiesta Bowl.
They lost to The University of Arkansas 29-16.
 Following the season, Snyder was named Woody Hayes Coach of the Year.

In the 2012 season, Snyder led the team to its first Big 12 Conference championship since 2003.
 The 2012 team started the season 10–0 and reached the school's first #1 ranking in the BCS standings, before falling to the Baylor Bears in week 11.
K-State represented the conference in the 2013 Fiesta Bowl, losing to the fifth-ranked Oregon Ducks 35–17.
 Following the season, Snyder won the Bobby Dodd Coach of the Year Award.

Snyder has held the head coaching position at Kansas State longer than any other coach.
His 215 wins are not only far and away the most in KSU history (no one else has reached 40 wins), but also more than all other KSU football coaches from 1928 to present combined (189 wins).
During his tenure, K-State  produced 34 AP All-Americans, 47 NFL Draft picks, and 46 first-team academic All-Americans.

On January 31, 2013, it was announced that Snyder's contract was extended through the 2017 season.

On August 9, 2018 it was announced that Bill Snyder had signed a 5-year extension that will run through the 2022 season, worth $3.45 million with $300,000 bonuses, and incentives with them to be determined after 2 years.

On December 2, 2018, Snyder announced his retirement from coaching college football.
Snyder finished his career with Kansas State with 215 victories and two Big 12 championships.
He is far and away the winningest coach in Kansas State history; no other coach has even crossed the 40-win mark.
Additionally, he accounted for over 40 percent of Kansas State's all-time wins as of 2018.
