Mlázovice is a market town in Jičín District in the Hradec Králové Region of the Czech Republic. It has about 600 inhabitants.

The village of Mezihoří is an administrative part of Mlázovice.

The name is derived from the personal name Mlaz, meaning "the village of Mlaz's people". Originally the name was Mlazovice, but in the 16th century it was distorted to Mlázovice because of its similarity with the word mlází ("young forest").

Mlázovice is located about 12 kilometres (7 mi) east of Jičín and 30 km (19 mi) northwest of Hradec Králové. It lies in the Jičín Uplands. The highest point is the hill Maxinec at 450 m (1,480 ft) above sea level. The Javorka River flows along the eastern municipal border.

The first written mention of Mlázovice is from 1360, when there was a fortress owned by Jiřík of Mlázovice. The owners of Mlázovice often changed. In 1424, during the Hussite Wars, the fortress and the village were burned down, but the village recovered. In 1540, during the rule of the Karlík of Nežetice family, Mlázovice was promoted to a market town. In 1594, Mlázovice was acquired by the Smiřický family and annexed to the Hořice estate.
