The Sheremetev family (Russian: Шереме́тевы) was one of the wealthiest and most influential noble families of Russia.

The family held many high commanding ranks in the Russian military, governorships and eventually the rank of Count of the Russian Empire. Notable members of the family include:

The village of Sheremetevo, which in turn gave name to the Sheremetyevo International Airport, is named after the family.

Russian surnames are gender sensitive, the masculine form of the name being Sheremetev (Шереметев) and the feminine being rendered as Sheremeteva (Шереметева). Two theories as to the origin of the surname obtain, both of which indicate a Tatar and eastern origin for the family. One theory proposes that the name originated with the Turkic Chuvash language word sheremet (шеремет), meaning "poor man," while the other theory suggests that the name originates with the Tatar/Turkic-Persian shir Akhmat, which literally translates to "Tiger Ahmet" and can be read as both "brave Ahmet" and "Pious Ahmet."
