牛耕式转行书写法（βουστροφηδόν，又译折行书）是一种古代书写方式。它出现在古代希伯来文和阿拉伯文、希腊文等的手稿之中。现今盲人的点字文也是用此方法书写。

现代的文本多数习惯将文本逐行逐行书写——从左边开始书写，当到了右方边缘时，便会由下一行的左边开始继续书写。在直排中文，从上方开始书写，到了下方边缘，便从整行右边的上方继续。但牛耕式则是一起连着书写，即若第一行是由左到右书写，第二行则由右至左书写，下一行又是由左至右。而且，每个字母在左至右的行的写法，跟在右至左的，是左右反转的。

希腊文βουστροφηδόν，βους是牛，στροφή是拐弯，整个字即「像牛犁田般拐弯」。

Boustrophedon /ˌbuːstrəˈfiːdən/ (Ancient Greek: βουστροφηδόν, boustrophēdon “ox-turning” from βοῦς, bous, “ox” , στροφή, strophē, “turn” and the adverbial suffix -δόν, "like, in the manner of"; that is, turning like oxen in ploughing) is a kind of bi-directional text, mostly seen in ancient manuscripts and other inscriptions. Every other line of writing is flipped or reversed, with reversed letters. Rather than going left-to-right as in modern English, or right-to-left as in Arabic and Hebrew, alternate lines in boustrophedon must be read in opposite directions. Also, the individual characters are reversed, or mirrored. It was a common way of writing in stone in Ancient Greece.
