Xiao (; Chinese: 蕭) is a Chinese-language surname. In the Wade-Giles system of romanization, it is rendered as Hsiao, which is commonly used in Taiwan. It is also romanized as Siauw, Shiao, Siaw, Siew, Siow, Seow, Siu, Shiu or Sui, as well as "Shaw" in less common situations, inspired by the transliteration of the surname of notable figures such as Irish playwright George Bernard Shaw and English actor Robert Shaw. It is the 99th name on the Hundred Family Surnames poem.
