The 31-year old Czech midfielder has signed an 18-month contract with the Rhineland-Palatinate outfit and his signing was welcomed by coach Thomas Tuchel.
"Jan Simak further expands our options in attack," he told the club's official website.
"He is a player who can directly help us."
Simak joined Stuttgart from Carl Zeiss Jena in 2007 and prior to that enjoyed stints with Hannover, Bayer Leverkusen and Sparta Prague.
