威廉·廷代尔（William Tyndale，又译廷岱勒、丁道尔、丁铎、廷德尔，1494年－1536年）是16世纪著名的基督教学者和宗教改革先驱，被认为是第一位清教徒。

在廷代尔的时代，罗马天主教教廷只允许拉丁文圣经，不容许私自翻译，并且只有神职人员可以拥有和诠释圣经。廷代尔却主张应该让普通老百姓都可透过读圣经来认识神，决心把圣经译成英文，于是被诬陷为异端，后来在比利时被杀害。

廷代尔是第一个把原文本圣经译为现代英语的圣经翻译家。后来著名的钦定版圣经有百分之九十采用了他的译本。2002年，廷代尔被英国广播公司选为最伟大的100名英国人。

William Tyndale (/ˈtɪndəl/; sometimes spelled Tynsdale, Tindall, Tindill, Tyndall; c.1494–1536) was an English scholar who became a leading figure in Protestant reform in the years leading up to his execution. He is well known for his translation of the Bible into English. He was influenced by the work of Desiderius Erasmus, who made the Greek New Testament available in Europe, and by Martin Luther. While a number of partial translations had been made from the seventh century onward, the spread of Wycliffe's Bible resulted in a death sentence for any unlicensed possession of Scripture in English—even though translations in all other major European languages had been accomplished and made available. Tyndale's translation was the first English Bible to draw directly from Hebrew and Greek texts, the first English one to take advantage of the printing press, and first of the new English Bibles of the Reformation. It was taken to be a direct challenge to the hegemony of both the Church of England and the laws of England to maintain the church's position. In 1530, Tyndale also wrote The Practyse of Prelates, opposing Henry VIII's divorce from Catherine of Aragon on the grounds that it contravened Scripture.
