The Pole becomes the first official signing of new manager Thomas Christiansen.
Klich was a first-team regular for the Dutch side throughout his debut season at the club, scoring six goals and providing four assists in a total of 30 appearances in all competitions.
The midfielder helped FC Twente secure a top seven finish which guaranteed Europa League football next season.
Klich has also proven himself on the international stage as he has made a total of 10 appearances for the Poland national team.
The Polish midfielder has secured one major trophy in his playing career which came in 2014 when PEC Zwolle won the Dutch Cup by beating giants Ajax 5-1 in the final, with Klich providing one assist.
The midfielder has made over 180 league appearances throughout his career and he has also experienced playing football in the lower leagues.
Leeds will be hoping that his arrival can help them mount a serious challenge for automatic promotion next season.
