Moscow Institute of Physics and Technology (Russian: Московский Физико-Технический институт), known informally as PhysTech (Физтех), is a leading Russian university, originally established during the Soviet Union. It prepares specialists in theoretical and applied physics, applied mathematics, and related disciplines.

MIPT is famous in the countries of the former Soviet Union, but is less known abroad. This is largely due to the specifics of the MIPT educational process (see "Phystech System" below). University rankings such as The Times Higher Education Supplement are based primarily on publications and citations. With its emphasis on embedding research in the educational process, MIPT "outsources" education and research beyond the first two or three years of study to institutions of the Russian Academy of Sciences. MIPT's own faculty is relatively small, and many of its distinguished lecturers are visiting professors from those institutions. Student research is typically performed outside of MIPT, and research papers do not identify the authors as MIPT students. This effectively hides MIPT from the academic radar, an effect not unwelcome during the Cold War era when leading scientists and engineers of the Soviet arms and space programs studied there.

The word "phystech," without the capital P, is also used in Russian to refer to Phystech students and graduates.

The main MIPT campus is located in Dolgoprudny, a northern suburb of Moscow. However the Aeromechanics Department is based in Zhukovsky, a suburb south-east of Moscow.​​​
