Matsudaira Narisawa (松平 斉善, 31 October 1820 – 15 September 1838) was the 15th daimyō of Fukui Domain under the Edo period Tokugawa shogunate in Echizen Province.
His childhood name was Taminosuke (民之助) or Sensaburō (千三郎)[1] In 1835, when Matsudaira Naritsugu (husband of Narisawa's sister, Asahime) died without an heir, Narisawa was chosen by the shogunate to become daimyō of Fukui Domain.
He departed Edo for his domain in June 1838, but died shortly after reaching Fukui in September of the same year.
Under most circumstances, this would have been cause for attainder of the domain; however, through the quick intervention of Asahime, a cousin (Matsudaira Shungaku) was chosen as his posthumous successor, and the official date of Narisawa's death was changed to show that a successor had been appointed before he died.
In 1837, the domain's Edo residence burned down, and was 20,000 ryō loan was obtained from the shogunate for its reconstruction.
