Matsudaira Sukekuni (松平 資訓, 1700 – May 9, 1752) was a hatamoto, and later a daimyō during mid-Edo period Japan.
In 1714, he entered into the administration of the Tokugawa shogunate as a minor hatamoto, and received Lower 5th Court Rank.
On the death of his brother-in-law, Matsudaira Suketoshi, the daimyō of Hamamatsu Domain in Tōtōmi Province in 1773, Sukekuni was adopted into the Honjō branch of the Matsudaira clan and inherited the 70,000 koku domain.
In 1741, he became a Sōshaban (Master of Ceremonies) in the administration of Edo Castle.
Sukekuni was married to a daughter of Arima Yorimoto, the daimyō of Kurume Domain.
