鲍里斯·米哈伊洛维奇（俄语：Борис Михайлович）被一些人认为是1248年至1263年间的莫斯科大公，不过较多意见认为后来的丹尼尔·亚历山德罗维奇是第一任莫斯科大公。

鲍里斯·米哈伊洛维奇是弗拉基米尔大公雅罗斯拉夫二世·弗谢沃洛多维奇的孙子、弗拉基米尔大公及莫斯科大公米哈伊尔·雅罗斯拉维奇·霍罗布里特的儿子、诺夫哥罗德公爵及弗拉基米尔大公亚历山大·涅夫斯基的侄子、莫斯科大公丹尼尔·亚历山德罗维奇的堂兄。

在鲍里斯·米哈伊洛维奇及其叔父亚历山大·涅夫斯基死后，亚历山大·涅夫斯基之两岁幼子丹尼尔·亚历山德罗维奇分得莫斯科为领土，长大后成为莫斯科大公，成为历代莫斯科大公和沙皇的始祖。所以鲍里斯·米哈伊洛维奇及其父米哈伊尔·雅罗斯拉维奇·霍罗布里特的莫斯科大公地位备受争议。

Boris Mikhailovich is, controversially, considered to have been Prince of Moscow from 1248 to 1263, preceding Daniil Aleksandrovich, who is more often named as the first Prince of Moscow.

Boris was the son of Mikhail Iaroslavich Khorobrit, who was the younger brother of Aleksandr Nevsky, and would thus have been Daniil's uncle. Boris' father was briefly Grand Prince of Vladimir in 1248, but Boris never seems to have held that title. Following Boris' death, Daniil took control of Moscow only in about 1283.
