145 (Ukrainian: Київський природничо-науковий ліцей № 145), is a secondary educational institution, located in Pechersk District of Kyiv, Ukraine.

In the early 1990s a considerable number of teachers of the Lyceum left (mostly for positions outside of the country), but the process was reversed later in the decade.

Programs in Mathematics and Physics were developed for the Lyceum in cooperation with the faculty of the Kyiv National University.

Several subject Olympiads are organized, with the winners proceeding to the nationwide and international level contests.

Lectures and courses are also taught by the university professors and members of the research staff of the NASU.
