Ume Kenjirō (梅 謙次郎, July 24, 1860 – August 26, 1910) was a legal scholar in Meiji period Japan, and a founder of Hosei University.

After an additional year of study at the Humboldt University of Berlin in Germany, he returned to Japan in 1890.

Together with Hozumi Nobushige and Tomii Masaaki, he is regarded as the father of Japan's civil law, which was put into effect in 1898.

In 1894, Ume was one of a group of lawyers who established the Tokyo Law School, the forerunner of present-day Hosei University, of which he served as president in 1899.

He was awarded the Order of the Sacred Treasure (1st class) on his deathbed, one day before he died.
