Hakuyū Taizan Maezumi (前角 博雄 Maezumi Hakuyū, February 24, 1931–May 15, 1995) was a Japanese Zen Buddhist teacher and rōshi, and lineage holder in the Sōtō, Rinzai, and Sanbo Kyodan traditions of Zen. He combined the Rinzai use of kōans and the Sōtō emphasis on shikantaza in his teachings, influenced by his years studying under Hakuun Yasutani in Sanbo Kyodan. He founded or co-founded several institutions and practice centers, including the Zen Center of Los Angeles, White Plum Asanga, Yokoji Zen Mountain Center and the Zen Mountain Monastery.
