Milan Emil Amruš (October 1, 1848 – May 26, 1919) was a Croatian physician, lawyer and politician, a two-term mayor of Zagreb.

In his capacity as mayor, he brought Nikola Tesla back from the United States in an effort to get the city electric lighting, but was unsuccessful.

The gasworks was moved out of the city center, and during this time the company Zagrebački zbor was started, the precursor to the Zagreb Fair.

In that role, Amruš started an effort to found technical faculties at the Universities, but could not achieve that goal until the end of World War I in 1918.

[1] Amruš had no children and was in fact known as a hardfisted person,[2] but in his will he left everything, including two major mansions at Zrinjevac and a rural estate in Zdenčina near Klinča Sela, to the city.
