Thawiwatthana Football Club (), better known as old name Sriracha FC (), is a Thai defunct professional football club based in Nakhon Pathom.
The club played their home games at the Suan Sunandha Rajabhat University Salaya Campus Stadium in Nakhon Pathom. They traditionally played in pink and blue. The club's official logo had a king cobra, hence their nickname the Killer King Cobra.
The club has somewhat become known as a yo-yo club in the Thai football scene, being relegated and promoted to and from the top flight on five successive occasions between 2008 and 2012. The sequence was broken in 2012 when they finished one place off the promotion spots in the 2012 Division 1 race.
