The Tenishev School was a pre-revolutionary secondary educational institution in St. Petersburg. It originated from a 3-class general education school founded in 1898 by Prince V. N. Tenishev and received the status of a commercial school in 1900. Initially, the school was located in a residential building on Zagorodny Avenue, but in 1900 it moved to a specially built building on Mokhovaya Street, funded by Tenishev.

The education at the school lasted 8 years, including seven general and one special class, and provided graduates with rights similar to those who completed a real school, with an emphasis on natural and mathematical disciplines. The curriculum was more extensive than in other educational institutions and included specialized subjects such as accounting, commercial arithmetic, commodity science, and economic geography. The main focus was on natural sciences, which were studied throughout all 8 years, primarily in laboratories. Practical classes were conducted in physics, chemistry, geography, and other subjects, with educational excursions actively used. The school had a greenhouse and an observatory. Latin was not taught, so graduates planning to enter university had to study it independently and take an exam in the city educational district. A semester system was introduced, like in higher educational institutions, allowing students to be promoted to the next class twice a year and retaining those lagging behind for only half a year.

The "Report on the State of Commercial Education in Russia for the 1903-4 Academic Year" noted that in the lower classes, education was based on classroom activities with a limit of 25 students. Homework was given in small amounts and was educational in nature. Fostering a serious attitude towards studies was facilitated by the absence of formal incentives such as promotion exams and grades. Student promotion was carried out by the decision of the pedagogical committee. The school placed great importance on physical and moral education, striving for cooperation with families, allowing parents to attend lessons and participate in parent meetings.

Students published the magazine "Tenishevets," and from 1914 to 1916, the lithographed magazine "Young Thought." The school's concert hall hosted performances, poetry and music evenings, as well as various meetings and congresses.

The first graduation took place in 1905. In 1918, the school came under the management of the People's Commissariat for Education. In November 1921, the building housed the Young Spectators' Theater. Currently, it is home to the Educational Theater "Na Mokhovoy" of the Russian State Institute of Performing Arts.
