# How do I center the title names of List of Figures and List of Tables?

\usepackage{tocloft}
\renewcommand{\cfttoctitlefont}{\hspace*{\fill}\Huge\bfseries}


But what do we use for the List of Figures and the List of Tables?

tocloft provides commans to change the formatting for the main lists: the ToC (Table of Contents), the LoT (List of Tables), and the LoF (List of Figures). For example, \cfttoctitlefont allows changes to the font of the ToC; the corresponding command for the LoF is obtained replacing the infix toc with lof in the command name: \cftloftitlefont, and the corresponding command for the LoT is obtained replacing the toc with lot: \cftlottitlefont.

To avoid repeating three times almost the same command in the documentation of the package, the author of the package decided to use a placeholder "Z" representing either toc, lof or lot, so to refer to the three commands discussed above, the documentation uses \cftZtitlefont.

\renewcommand{\cfttoctitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftaftertoctitle}{\hspace*{\fill}}
\renewcommand{\cftlottitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftafterlottitle}{\hspace*{\fill}}
\renewcommand{\cftloftitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftafterloftitle}{\hspace*{\fill}}


A complete example:

\documentclass{article}
\usepackage{tocloft}
\usepackage{showframe}& just for the example

\renewcommand{\cfttoctitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftaftertoctitle}{\hspace*{\fill}}
\renewcommand{\cftlottitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftafterlottitle}{\hspace*{\fill}}
\renewcommand{\cftloftitlefont}{\hspace*{\fill}\Huge\bfseries}
\renewcommand{\cftafterloftitle}{\hspace*{\fill}}

\begin{document}

\tableofcontents
\listoffigures
\listoftables

\end{document}


The showframe package was used just to have a visual guide for the page layout.
