白犀牛，又叫做方唇犀牛（Ceratotherium simum），係現存嘅犀牛裏面數量較多嘅一種，亦係鍾意群居嘅犀牛。而家有兩個亞種：南方亞種（C. s. simum），截至2007年底有17,480隻野生品種（IUCN 2008）；北方亞種（C. s. cottoni）就非常稀有，全球可能少過13隻（包括9隻養住同4隻野生，但嗰4隻自2006年後就冇人再搵到，可能已經絕種）。

白犀牛其實唔應該叫做白犀牛嘅。佢喺南非土著——波爾人嘅土語裏面，係叫做Wijde Rhino，即係「寬大嘅犀牛」咁解，只不過早年去非洲碰運氣嘅歐洲機會主義誤將Wijde Rhino翻譯做White Rhino，即係「白色嘅犀牛」，於是就將錯就錯，用到而家，成為同黑犀牛對比嘅名^]

 The white rhinoceros or square-lipped rhinoceros (Ceratotherium simum) is the largest species of rhinoceros that exists. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 17,460 wild-living animals at the end of 2007 (IUCN 2008), and the much rarer northern white rhinoceros. The northern subspecies has very few remaining, with four confirmed individuals left, with only four still able to reproduce (Including those in captivity).^[
