Shinpei Ogura (小倉進平, Ogura Shinpei; June 4, 1882 – February 8, 1944) was a Japanese linguist who studied the Korean language. Ogura is well-known in Korea for his contributions to Korean linguistics, with much of his field work and studies considered invaluable resources even in recent years. Ogura made a number of landmark firsts in the field; he was the first person to decipher hyangga poetry documents. He is also considered the first modern researcher of Korean dialects, and traveled throughout the peninsula doing field research. The data he collected on dialects are still widely referred to, especially because the division of Korea in 1945 has made it difficult to study dialects on opposite ends of the peninsula. In Korean, he is sometimes called Soch'ang Chinp'yŏng (Korean: 소창진평), the Korean Hanja reading of his name.
