The n x n matrices, for any n>1, with entries in almost any ring, are going to be an example.

R={a+bi+cj+dk ;a,b,c,d are real no.s}
Here,i^2=j^2=k^2= -1
and i.j=k , j.k=i, k.i=j
and i.j= -j.i , j.k= -k.j , k.i= -i.k
Infact it is a division ring(a ring in which every non zero element is invertible but is not commutative)
