  Throughout this paper, $R$ is an associative ring (not necessarily
commutative) with identity and $M$ is a right $R$-module with unitary. In this
paper, we introduce a new concept of $\phi$-prime submodule over an associative
ring with identity. Thus we define the concept as following: Assume that $S(M)$
is the set of all submodules of $M$ and $\phi:S(M)\rightarrow
S(M)\cup\{\emptyset\}$ is a function. For every $Y\in S(M)$ and ideal $I$ of
$R,$ a proper submodule $X$ of $M$ is called $\phi$-prime, if $YI\subseteq X$
and $YI\nsubseteq\phi(X),$ then $Y\subseteq X$ or $I\subseteq(X:_{R}M)$. Then
we examine the properties of $\phi$-prime submodules and characterize it when
$M$ is a multiplication module.
