爱因斯坦塔（ Einsteinturm）是位于德国波茨坦爱因斯坦科学公园内的一座天文台，由埃瑞许·孟德尔松设计。

它内部容纳一座太阳望远镜，由天文学家厄文·芬利（Erwin Finlay-Freundlich）设计。该望远镜进行实验和观察来验证（或否定）爱因斯坦相对论;。爱因斯坦塔最初于1917年左右构思，1919年完工，并于1924年开始运作，虽然爱因斯坦从来没有在那里工作，他仍支持望远镜建设和运营。目前爱因斯坦塔仍在运作，是莱布尼茨天体物理研究所（Leibniz Institute for Astrophysics Potsdam）的一部分。

The Einstein Tower (German: Einsteinturm) is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany built by Erich Mendelsohn. It was built on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate (or disprove) Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam. Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory.
