Xueshan or Sekuwan (in Atayal, formerly known as Mount Sylvia among others) is a mountain in the Heping District of Taichung, Taiwan.

It is located in the Shei-Pa National Park and is visible in good weather from hills near Taiwan's capital Taipei.

Japanese historian Taira Shidehara suggests that 雪 is short from 雪高翁, transliteration of Atayal Sekoan or Sekuwan which means "cracking into gravel".

Its name was accordingly changed to Tsugitakayama (次高山), meaning "Next-" or "Second-Highest Mountain", in 1923.

International hikers can apply for a park entry permit between 35 days and 4 months in advance.
