唐三藏或唐僧，是著名小说《西游记》中主要角色之一，其原型是玄奘法师，小说人物是佛祖弟子罗汉金蝉子转世，虽然作者取材于玄奘大师西行求法的故事，但基本上仍属于作者构想、创造的人物和故事，不应将之误解为史实或归类为历史小说。其中著名的孙悟空、猪八戒（猪悟能）和沙悟净，以及西游除魔降妖生动活泼的丰富情节，显然并非记述玄奘西游天竺的故事，而是另有其独特而广泛的哲学、人文意义和社会、艺术价值。

佛教界对《西游记》有两种截然不同的看法，近代禅宗高僧虚云大师指斥《西游记》是道教徒写来诋毁佛教的作品<ref《虚云和尚方便开示》</ref>。

Xuanzang (Hsuan-tsang; Chinese:玄奘; pinyin:Xuánzàng) is a central character in the novel Journey to the West by Wu Cheng'en. The character is based on the historical Buddhist monk Xuanzang.

He is mainly referred to as Tang Sanzang in the novel. The title Sanzang refers to his mission to seek the Sanzangjing, or the "Three Collections of (Buddhist) Scriptures". In some English translations of Journey to the West, the title is rendered as Tripitaka which is the original Sanskrit term for the Sanzangjing. He is also widely known as Tang Seng, which is a courtesy name that, like the former name, Tang Sanzang, reflects his status as an oath brother of Emperor Taizong of the Tang Dynasty.
