Let R be a commutative ring with a nonzero identity. In this paper, we introduce the concept
of weakly 2-prime ideal which is a generalization of 2-prime ideal and both are generalizations of prime
ideals. A proper ideal I of R is called weakly 2-prime ideal if whenever a,b ∈ R with 0 ab ∈ I, then a2 or b2
lies in I. A number results concerning weakly 2-prime ideals are given. Furthermore, we characterize the
valuation domain and the rings over which every weakly 2-prime ideal is 2-prime and rings over which
every weakly 2-prime ideal is semi-primary (i.e
√
I is a prime ideal). We study the transfer the notion of
weakly 2-prime ideal to amalgamted algebras along an ideal A ▷◁f J
