Yanagisawa Yoshiyasu was a prominent shogunal advisor, serving as Tairô from 1706 to 1709.

Previously known as Fusayasu and Yasuakira, he was at some point granted the privilege of the use of the clan name Matsudaira. The son of a samurai, he became soba yônin under Shogun Tokugawa Tsunayoshi in 1688. Yoshiyasu became lord of the 150,000 koku domain of Kôfu in 1704, and then rôjû and Tairô in 1706, serving in that position until 1709.

He had the Rikugien gardens in Edo built sometime around 1699-1706.
