Zheng Xie (Chinese: 鄭燮; pinyin: Zhèng Xiè), courtesy name Kerou (克柔), art name Banqiao (板橋) or Banqiao Daoren (板橋道人), commonly known as Zheng Banqiao (鄭板橋), was a Chinese official, painter and calligrapher of the Qing dynasty.

He began life in poverty, but rose in the imperial examination system to become a magistrate in Shandong.

When he was reportedly criticized for building a shelter for the poor, he resigned.

Zheng was also a calligrapher who created a new calligraphy style influenced by his orchid drawings.

He preferred to write about ordinary people in a natural style.
