There are a number of ways. Here's using the enumerate package:

enter image description here

\documentclass{article}
\usepackage{enumerate}% http://ctan.org/pkg/enumerate
\begin{document}
\begin{enumerate}[I]
  \item One
  \item Two
  \item Three
\end{enumerate}

\begin{enumerate}[i]
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

Here's another method via the enumitem package. It yields the same output as above:

\documentclass{article}
\usepackage{enumitem}% http://ctan.org/pkg/enumitem
\begin{document}
\begin{enumerate}[label=\Roman*]
  \item One
  \item Two
  \item Three
\end{enumerate}

\begin{enumerate}[label=\roman*]
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

And then, without any packages:

\documentclass{article}
\renewcommand{\labelenumi}{\theenumi}
\begin{document}
\renewcommand{\theenumi}{\Roman{enumi}}%
\begin{enumerate}
  \item One
  \item Two
  \item Three
\end{enumerate}

\renewcommand{\theenumi}{\roman{enumi}}%
\begin{enumerate}
  \item One
  \item Two
  \item Three
\end{enumerate}
\end{document}

There's also the paralist package, that works just like enumerate in this case. — Christian, May 02 '12 at 06:06
Unfortunately, with paralist the 8th item is misaligned (with enumerate it's correct). — Javier Bezos, May 02 '12 at 07:04
Side note, enumitem is recommended What's the difference between the enumerate and enumitem packages? - TeX - LaTeX Stack Exchange (although it's listed later) — user202729, Apr 22 '22 at 12:10

If you want to type:

I.

II.

III.

Use:

\documentclass{article}
\begin{document}
\usepackage{enumerate}
\begin{enumerate}[I.]
  \item my text
  \item my text
  \item my text
\end{enumerate}

Another possibility for [I.] is [(I)], which gives:

(I)

(II)

(III)

The question is how to have lowercase roman numeral, not to add a period/dot after the Roman numeral. – Guido Apr 02 '13 at 11:29

but this was useful information, so thanks. – Tasos Papastylianou Jan 01 '17 at 14:46
Unfortunately this package adds the side-effect of changing the indentation for the items - is there any way to avoid this change? – Dmitri Zaitsev Jul 05 '19 at 01:53
@DmitriZaitsev You might want to check out enumitem package (with package option shortlabels. It's more customizable than enumerate. – Caleb Stanford Nov 19 '19 at 01:36

For those using Spanish with babel package, the enumerate option \begin{enumerate}[i] does not work. To make it work, load the babel package with this option:

\usepackage[spanish,es-lcroman]{babel}

Explanation:

Spanish babel forces the use of upper case. As the manual states:

Traditional Spanish typography discourages the use of lowercase Roman numerals.

The manual justifies this choice referencing the book José Martínez de Sousa, Diccionario de tipografía y del libro, Madrid, Paraninfo, 3.a ed., 1992.

If you're using the beamer class, try something like:

\setbeamertemplate{enumerate item}{(\roman{enumi})}

or

\setbeamertemplate{enumerate subitem}{(\roman{enumii})}

Just use [label=(\roman*)] – Smaillns May 31 '19 at 11:58
@Smaillns, have you tested it? This would require an extension package. – PatrickT Jun 02 '19 at 14:20
\usepackage{enumitem} – Smaillns Jun 05 '19 at 10:32
Note: you can remove the braket "()", and add what you want, for instance \begin{enumerate}[label=\roman*] – Smaillns Jun 05 '19 at 10:40
if we use [label=\Roman*] we will get letter on Uppercase instead – Smaillns Jun 05 '19 at 10:44

This is covered by Werner's answer, while my answer was focused on the beamer class specifically. – PatrickT Jun 05 '19 at 16:47
@Smaillns Why asterisk is needed? – ado sar Aug 18 '19 at 12:58
