Mecklenburg-Güstrow was a state of the Holy Roman Empire in Northern Germany, that existed on three separate occasions ruled by the House of Mecklenburg at Güstrow.

A first short-lived predecessor existed after the death of Henry IV, Duke of Mecklenburg, in 1477 and the partition of the land among his sons in 1480, when Albert VI received the estates of the former Lordship of Werle around Güstrow. Nevertheless, Albert died without issue in 1483 and his lands were again inherited by his younger brother Magnus II, Duke of Mecklenburg-Schwerin.

When Magnus died in 1503, his sons Henry V and Albert VII at first ruled jointly over the entire Mecklenburg duchy until its renewed division by the 1520 Neubrandenburg Treaty. Albert, a fierce opponent of the Protestant Reformation, had insisted on the partititon and became duke of Mecklenburg-Güstrow, while his brother Henry retained Mecklenburg-Schwerin. However Mecklenburg de jure remained undivided, both brothers held the title of Duke of Mecklenburg and, as Henry only left one insane son when he died in 1552, the Schwerin lands fell back to Albert's sons Ulrich III and John Albert I.

At this time John Albert and Ulrich had ruled jointly over the Güstrow lands, but now came into conflict over the inherited Schwerin part. The controversy was finally decided in 1556 by the Ruppin dictum of Joachim II Hector, Elector of Brandenburg: John Albert I received Schwerin while Ulrich remained Duke of Mecklenburg-Güstrow. Nevertheless, Ulrich died without heirs in 1603 and Güstrow fell back to John Albert's grandchildren Adolf Frederick I and John Albert II, joint rulers of Mecklenburg-Schwerin from 1610 onwards.
