The Razdolnaya (Russian: Раздольная, formerly: Суйфун Suyfun)[1] or Suifen (simplified Chinese: 绥芬河; traditional Chinese: 綏芬河; pinyin: Suífēn Hé) is a river in People's Republic of China and Russia.

[2] Suifen is the Manchu word ᠰᡠᡳ᠌ᡶ᠋ᡠᠨ (suifun) for awl, referring to the shape of a species of Oncomelania snail.

In 1972, in the aftermath of the Zhenbao Island incident (1969), toponyms of Chinese origin in Primorsky Krai were replaced en masse with newly designed Russian names; as part of this project, the Russian part of the Suifen received the name Razdolnaya, which can be translated from Russian as "widely flowing".

Downstream of the city, the river enters Russian territory, and flows into Amur Bay through Khanka Lowlands.
