# Suppressing in the word “Chapter N” from header, documentclass: report

I want to suppress the word "Chapter n" from my header. I want to have only the chapter title in the header e.g. "Introduction" not as "Chapter 1. Introduction" The document class is report. Here is the full code of my document;

\documentclass[a4paper,12pt,twoside]{report}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[nottoc]{tocbibind}
\usepackage[nottoc]{tocbibind}
\usepackage{titlesec}
\titleformat{\chapter}{\normalfont\huge\bf}{\thechapter}{20pt}{\huge\bf}
\renewcommand{\baselinestretch}{1.5}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{amsmath}
\usepackage{ccaption}
\usepackage{subcaption}
\graphicspath{{images/}}
\usepackage[a4paper, width=150mm, top=25mm, bottom=45mm, bindingoffset=6mm]{geometry}
\usepackage{fancyhdr}
\pagestyle{fancy}
\renewcommand{\chaptername}{}

\fancyfoot{}
\setcounter{secnumdepth}{4}
\pagenumbering{Roman}
\usepackage{cite}

• if i understand the question correctly, all you want to do is omit the "chapter n" from above the chapter title. if that is true, then you can just use \chapter*{...} (the asterisk * gives the instruction to omit the number from the heading). with the report class, this also omits the entry for the chapter from the table of contents, but that can be added back explicitly with \addcontentsline. (search for that in other questions.) – barbara beeton Apr 27 '16 at 21:18

If you want to keep the chapter name in the header line in all-caps, insert the instruction

\def\chaptermark#1{\markboth{\MakeUppercase{#1}}{}}


in the preamble.

If you do not want the chapter name rendered in all-caps, use the instruction

\def\chaptermark#1{\markboth{#1}{}}

• Note that the proposed solution method is specific to the report document class. Other solutions may be needed if one uses other document classes. – Mico Apr 27 '16 at 15:12

If I understand well what you want, it's easy to do with titleps, a companion to titlesec:

\documentclass[a4paper,12pt,twoside]{report}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[nottoc]{tocbibind}
\usepackage[pagestyles]{titlesec}
\titleformat{\chapter}{\normalfont\huge\bfseries}{\thechapter}{20pt}{}
\renewcommand{\baselinestretch}{1.5}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{amsmath}
\usepackage{ccaption}
\usepackage{subcaption}
\graphicspath{{images/}}
\usepackage[a4paper, width=150mm, top=25mm, bottom=45mm, bindingoffset=6mm]{geometry}
\setcounter{secnumdepth}{4}
\pagenumbering{Roman}
\usepackage{cite}

\usepackage{lipsum}

\newpagestyle{ownstyle}{%
\setfoot{}{}{}
