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 byfinitely many involutions. The number of elements in his generating set dependslinearly on $g$ and $n$. In the case of $n=0$, Szepietowski found an involutiongenerating 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. Inthis thesis, for $n \geq 0$, we prove that ${\mathcal N}_{g,n}$ is generated byeight involutions if $g \geq 13$ is odd and by eleven involutions if $g \geq14$ is even.
