Zsófia Bosnyák (Slovak: Žofia Bosniakova, Nagysurány (Šurany), June 2, 1609 – Sztrecsnó (Strečno), April 28, 1644) was a Hungarian noble and wife of Count Ferenc Wesselényi.
At the age of 21, as a result of the mediation of cardinal Péter Pázmány, she married Ferenc Wesselényi.
After Bosnyák's father died of cholera in 1634, her husband Ferenc Wesselényi took over the duty of the captain at the Fülek Castle.
Wesselényi rarely came home to his family which, in the meantime, moved to Vágtapolca (Teplička nad Váhom) on account of many attacks against Fülek by Turkish soldiers.
Every year on Assumption Day (15 August), many people from the neighborhood came to visit her glass-covered coffin.
