Matthias Plachta (born 16 May 1991) is a German professional ice hockey forward who is currently playing for Adler Mannheim of the German DEL. He is the son of former German-Polish-Silesian player and former coach of the Poland men's national ice hockey team, Jacek Płachta.
Plachta played for Schwenningen and Mannheim as a junior and made his debut in Germany's second division for Heilbronn during the 2008–09 season. The following season, he logged first minutes in Germany's top-flight Deutsche Eishockey Liga (DEL) with Adler Mannheim. After six seasons in the DEL, including winning the title with Mannheim in 2015, and having secured a role in the German national team, Plachta was signed to a one-year entry-level contract with the Arizona Coyotes of the National Hockey League (NHL) on 28 May 2015.
In his debut North American season in 2015–16, Plachta was assigned to Arizona's AHL affiliate, the Springfield Falcons. In 46 games with the Falcons, Plachta compiled 2 goals and 7 points before he was traded by the Coyotes on trade deadline day along with a conditional 7th round draft pick in 2017 to the Pittsburgh Penguins in exchange for Sergei Plotnikov on 29 February 2016. Plachta played a total of 30 contests for Pittsburgh's AHL affiliate Wilkes-Barre Scranton Penguins during the season.
Having not been given the opportunity to play in the NHL during the season, and with Pittsburgh opting not to extend a qualifying offer, Plachta headed back to Germany, returning to Adler Mannheim on 30 June 2016 with the signing of a four-year deal.
He represented Germany at the 2018 IIHF World Championship.
