Yōnen 榮然 (fl. late 12th to mid-13th c.) was a Japanese Shingon master of the Chū’in-ryū 中院流 transmission line on Kōyasan, in the generation following Kōnen 興然 (1121–1203). His precise lifedates are not securely recoverable. His sole surviving work KR6t0207 Shī kǒu (Shiku) records the master’s-mouth oral transmissions of the Kōyasan Chū’in-ryū lineage in four fascicles.
Surviving work in the Kanripo corpus: KR6t0207 Shiku (4 fasc.).
