Namiki Gohei I (Japanese: 並木五瓶初代; 1747 – June 2, 1808) was a Kabuki playwright active in Kyoto, Edo and Osaka. He wrote over 100 plays, mostly in the genres of jidai-mono (historical) and sewa-mono (current events). Born in the Doshōmachi district in Osaka in 1747, Gohei was a student of the playwright Namiki Shōzō I. By 1775 he was already the main playwright for the Hayakumo-za Kabuki theatre in Kyoto.
