  Let $N_{g,n}$ denote the closed non-orientable surface of genus $g$ with $n$
punctures and let ${\mathcal N}_{g,n}$ denote the mapping class group of
$N_{g,n}$. Szepietowski showed that ${\mathcal N}_{g,n}$ is generated by
finitely many involutions. The number of elements in his generating set depends
linearly on $g$ and $n$. In the case of $n=0$, Szepietowski found an involution
generating set in such a way that the number of its elements does not depend on
$g$, showing that ${\mathcal N}_{g,0}$ is generated by four involutions. In
this thesis, for $n \geq 0$, we prove that ${\mathcal N}_{g,n}$ is generated by
eight involutions if $g \geq 13$ is odd and by eleven involutions if $g \geq
14$ is even.
