Ang igneous rocks ay isa sa tatlong pangunahing uri ng mga bato. Ito ay tumutukoy sa mga batong nagmula sa natuyong lava o magma ng  mundo na kadalasan ay inilalabas mga bulkan.

Maaring mahati sa dalawang klase ang igneous rocks:
Extrusive ang isang igneous rock kung ito ay naubo sa labas ng lupa.
At Intrusive naman ito kung nabuo sa loob.

Igneous rock is formed through the cooling and solidification ofmagma or lava. Igneous rock may form with or withoutcrystallization, either below the surface as intrusive(plutonic) rocks or on the surface as extrusive(volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either a planet'smantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Over 700 types of igneous rocks have been described, most of them having formed beneath the surface of Earth's crust
