R' Ovadiah ben Abraham of Bartenura (c. 1445-c.1515) wrote a commentary of the Mishnah that has been printed in almost every edition of the Mishnah since it was first published in Venice in 1548. The commentary, popularly called “The Bartenura” is mainly based on discussions in the Gemara and the Rambam's Mishnah commentary. The Bartenura is particularly valuable to Mishnah learners due to the inclusion of a summary of the Talmudic discussions along with the accepted opinions.
