Maksimas Katche (German: Wilhelm Johannes Arwed Max Kattchée, Russian: Макс Арведович Катхе, 5 November [O.S.

Katche chaired the Lithuanian delegation that negotiated and signed the Suwałki Agreement on 7 October 1920 with Poland.

Katche was born into a family of millers of Baltic German descent and Lutheran faith.

He soon took command of the Panevėžys Group and helped plan the Lithuanian offensive which pushed the invading Bolshevik forces across the Daugava River by end of August 1919.

He was a member of a Lithuanian delegation sent to the League of Nations in Geneva to negotiate with Poland regarding Vilnius Region in September 1921.

[1] In August 1922, Kazys Ladiga submitted a complaint that a "Russian monarchist" party was active in the Lithuanian military and that Katche was part of it.

[5] Ladiga was punished with 7-day arrest for false report but Katche resigned on 7 October 1922 (officially, for health reasons).

[1] His grave stone disappeared during the Soviet period and the exact location of his burial has long been debated.
