Hsu Kun-yuan (Chinese: 許崑源; pinyin: Xǔ Kūnyuán; Pe̍h-ōe-jī: Khó͘ Khun-goân; 1 May 1957 – 6 June 2020) was a Taiwanese politician.

A Kaohsiung native, he and his elder brother Hsu Kun-lung (許昆龍) participated in tangwai movements in the 1980s, and they joined the Democratic Progressive Party (DPP) in 1986.

However, Hsu Kun-lung's reputation was tarnished after being involved in a criminal case where two policeman were killed.

As a result, Hsu Kun-yuan decided to continue his brother's deeds, and further his political career.

[4] Hsu jumped to his death from his apartment in Kaohsiung on 6 June 2020, hours after the Han Kuo-yu mayoral recall vote.
