Hagbart (or Hagbard) Emanuel Berner (12 September 1839 – 24 January 1920) was a Norwegian lawyer, Liberal Party politician and newspaper editor.

He was the first editor-in-chief of the liberal newspaper Dagbladet and the co-founder (with Gina Krog) and first president of the Norwegian Association for Women's Rights.

[1] In Christiania he befriended intellectuals such as Ernst Sars and Aasmund Olavsson Vinje, and became politically active and a supporter of the Nynorsk language.

[4] His demand for a "clean" Norwegian flag, instead of the then-flag with a union badge (popularly known as Sildesalaten), led to political turbulence in 1879.

Berner co-founded the Norwegian Association for Women's Rights in 1884, together with Gina Krog, and was the organization's first president.
