In the spring of 1566, Zrinski found himself stationed in Szigetvár, a crucial fortress along the shortest route to Vienna. This was when the Ottoman sultan Suleiman the Magnificent led a massive army on his second attempt to conquer Vienna, deciding to first seize Szigetvár. Despite being given the option to depart by the new king, Maximilian II, Zrinski chose to stay, emphasizing the lives of thousands relying on the fortress's defense. With strategic preparations underway, Zrinski braced for the impending confrontation with the Sultan. Suleiman's forces reached Belgrade by June 27 after an arduous march. Upon learning of Zrinski's successful attack on Turkish forces at Siklós in July, Suleiman diverted his attention from Eger to focus on eliminating Zrinski's threat at Szigetvár.

For over a month, from August 5 to September 7, Zrinski valiantly defended Szigetvár with a small force of approximately 2,300–2,500 soldiers, mainly Croats, against the vast Ottoman army of over 100,000 soldiers and 300 cannons led by Suleiman himself. Despite the lack of promised reinforcements and Suleiman's offer of Croatian land, Zrinski remained resolute. The siege culminated in a desperate and suicidal charge led by Zrinski on September 7, 1566. Although Suleiman passed away from natural causes a day before the Ottomans could claim victory, Zrinski met his demise during the charge, shot by a Janissary with a musket. His head, reportedly offered as a reward, was buried by his son Juraj IV Zrinski and others at the Pauline monastery in Sveta Jelena, Šenkovec, Croatia. The fate of his body remains uncertain, with conflicting accounts suggesting it may have been burned or buried near the battlefield. A tombstone in Čakovec, Croatia, believed to belong to Nikola IV Zrinski, possibly marks the site where his head was interred. Additionally, artifacts including his sabre, helmet, and a silk robe, potentially worn during Maximilian II's 1563 coronation, are preserved in the Kunsthistorisches Museum in Vienna.
