Abstract : Let $S$ be a commutative semigroup with $0$ and 1. A proper ideal $P$ of $S$ is {\it weakly prime} if for $a,b \in S$, $0 \ne ab \in P$ implies $a \in P$ or $b \in P$. We investigate weakly prime ideals and related ideals of $S$. We also relate weakly prime principal ideals to unique factorization in commutative semigroups.
