Khao Soi Dao Wildlife Sanctuary (Thai: เขตรักษาพันธุ์สัตว์ป่าเขาสอยดาว) is a wildlife sanctuary in Thailand's Chanthaburi Province. It covers the area around Khao Soi Dao Tai and Khao Soi Dao Nuea (south and north Soi Dao mountains), the two highest peaks in the Chanthaburi Mountains of Eastern Thailand, which form part of the much larger Cardamom Mountains extending well into Cambodia.
The mountains are covered in tropical rainforest and the Chanthaburi River originates from the Khao Soi Dao Tai mountain. The wildlife sanctuary neighbours the smaller Khao Khitchakut National Park to the south and Khao Sip Ha Chan National Park and Khao Ang Rue Nai Wildlife Sanctuary to the northwest.
