The lattices of eight- and ten-dimensional Euclidean space with irreducible automorphism group or, equivalently, the conjugacy classes of these groups in $\mathrm {GL}_n(\mathbb {Z})$ for $n = 8,10$, are classified in this paper. The number of types is 52 in the case $n = 8$, and 47 in the case $n = 10$. As a consequence of this classification one has 26, resp. 46, conjugacy classes of maximal finite irreducible subgroups of $\mathrm {GL}_8(\mathbb {Z})$, resp. $\mathrm {GL}_{10}(\mathbb {Z})$. In particular, each such group is absolutely irreducible, and therefore each of the maximal finite groups of degree 8 turns up in earlier lists of classifications.
