Ozolmuiža Manor (Latvian: Ozolmuižas kungu māja, German: Gut Lappier) is an Early Classicism style manor house built for Count George Johann von Mellin at the end of the 18th century in Brīvzemnieki Parish, Limbaži Municipality, in the Vidzeme region of Latvia.

In 1542 manors were divided and Ozoli got the children of his married sister Elisabeth, by name Rosenid.

According to Herbord Karl Friedrich Bienemann von Bienenstamm [de], the size of the manor in 1816 was 12 and 5/6 adramaa [et], with 258 male and 273 female souls.

It was later owned by Friedrich von Ranitz and Bartholomäus Patkul Ķieģeļi Manor [et].

In 1598, the manor was bought by Heinrich Tiesenhausen from Konguta vassal castle [lv] for 6000 Red złoty.

[7] The main building was built at the end of the 18th century, when the manor was owned by Georg Johann von Mellin.

Five other furnaces, two ceilings and one hall interior of this manor are under state protection as art monuments.
