Tenrin Fūin 天倫楓隱 (fl. mid-16th century; active 1560s), Late-Muromachi → Sengoku-period Japanese Zen master who compiled the Sho-ekō shingi-shiki 諸廻向清規式 (KR6t0284) — the principal Edo-period Zen ritual-formulary for dedication-rites (ekō 廻向). The compilation colophon identifies him as the “remote dharma-descendant of Eigen [-ji], currently residing at Tenrin-[zan], kobitsu Fūin” (永源遠孫現住天倫比丘楓隱) and dates his redaction to the Eiroku era (永祿太歳 — the cyclical-binom “丙丑” is a graphical error for either 丙寅 / Eiroku 9 / 1566 or 乙丑 / Eiroku 8 / 1565; the precise year is unrecoverable from the corrupt graph).
Beyond this colophon-identification, no separate biographical record of Tenrin Fūin survives, and his lifedates are not preserved in extant lineage charts. The reference to “Eigen remote descendant” (永源遠孫) places him in the Eigen-ji 永源寺 lineage — most probably the Ōmi Rinzai Eigen-ji descending from 元光 Jakushitsu Genkō, but possibly a Sōtō affiliate of the same name. The text combines liturgical formulae that became standard in both Rinzai and Sōtō Edo-period ritual practice, and the work’s status in later monastic-rules transmission is ecumenical.
