Andrzej Kusionowicz Grodynski (22 October 1861 – 24 July 1925), baptized as Andrzej Szymon Kusionowicz, was a Polish lawyer who worked as a Silesian circuit judge based in Cieszyn for much of his career.
Kusionowicz was also the editor of Gwiazdka Cieszynska from 1889 to 1890.
An associate of Pawel Stalmach (cs), who founded Gwiazdka Cieszynska, he was also a friend of Józef Londzin (pl) with whom he shared the early vision of Cieszyn Silesia joining Galicia in a new Polish state independent of Austrian rule.
On 7 September 1906 Kusionowicz changed his surname to Grodynski and was later appointed President of the Silesian Court of Appeal in Katowice.
Following World War I (WWI) he represented the Polish High Court in Kraków for the legal transitioning of Silesia into the newly independent Poland.
