Ivo Krbek (23 August 1890 – 17 January 1966) was a Croatian politician, lawyer, lecturer, and academic in the Kingdom of Yugoslavia, the Independent State of Croatia, and the Socialist Federal Republic of Yugoslavia.

After receiving a law degree from the university several years later, Krbek began his lengthy tenure as a professor of administrative law at that institution, which lasted for more than fifty years.

His time at the university was interrupted only once, by his two-year term as the 23rd mayor of Zagreb from 1932 to 1934.

On 17 October 1958, Krbek was honored by being inducted into the Slovenian Academy of Sciences and Arts as a full member, a very distinguished position, particularly for an ethnic Croatian.
