Matsudaira Shigetomi (松平重富, 25 December 1748 – 30 July 1808) was the 12th daimyō of Fukui Domain under the Edo period Tokugawa shogunate in Echizen Province.
On the death of his elder half-brother, Matsudaira Shigemasa of Fukui Domain in 1758, he was posthumously adopted as heir and became daimyō.
During his tenure, he attempted to make fiscal reforms; however, damage caused by heavy snow, fires, windstorms, flood and epidemics in consecutive years thwarted his efforts, and the domain’s finances continued to deteriorate.
This resulted in higher rice prices and great public dissatisfaction, cumulating in a massive riot in Fukui in 1768.
As a close relative of the shogunal house Shigetomi was uncle to Tokugawa Ienari, the domain was able to call on the central government for financial assistance.
