The Iron Moonhunter (Chinese: 追月號; pinyin: Zhuī yuè hào; Jyutping: Zeoi1 jyut6 hou6) is a short children's picture book published in 1977, written and illustrated by the activist Kathleen Chang.

The book purportedly retells a Chinese-American myth set in the Sierra Nevada mountains during the construction of the First transcontinental railroad, starting in the fall of 1866.

Perhaps it's a fairy tale our grandparents concocted so we would think of the bitter past with wonder and pride; perhaps it's an explanation of abandoned railroad tracks in the Sierras that seem to lead nowhere; and perhaps it's true.

[2][3] Sau-ling Cynthia Wong speculates that as it is supposedly based on an unpublished private oral history, the Iron Moonhunter may have been invented by Chin, who was married to Chang in the early 1970s.

The Iron Moonhunter was dramatized by Calleen Sinnette Jennings, Mary Hall Surface, Eric Wilson (book & lyrics); Deirdre Kelly Lavrakas (concept); and Deborah Wicks La Puma (music & lyrics) as part of Walking the Winds: American Tales, an original musical which was commissioned by the Kennedy Center, where it premiered in 1996.
