A Manual for Writers of Research Papers, Theses, and Dissertations (published by the University of Chicago Press and often referred to simply as Turabian), is a style guide for writing and formatting research papers (such as the arrangement and punctuation of footnotes and bibliographies). The style described in this book is commonly known as Turabian style, after the book's original author, Kate L. Turabian.

The Chicago and Turabian styles are nearly identical.
Kate Turabian, the dissertation secretary at the University of Chicago for over 30 years, developed her guide for students and researchers writing papers, theses, and dissertations. Her manual is based on the University of Chicago Press's Manual of Style and departs from it in few places. "Turabian," as her guide is called, synthesizes the rules most important for students' papers and other scholarly research not intended for publication, and omits some of the publishing details and options that "Chicago" provides.
