We study low-energy dynamics of three-dimensional $\mathcal{N}=2$ $SU(N)$"chiral" gauge theories with $F$ fundamental and $\bar{F}$ anti-fundamentalmatters without a Chern-Simons term. Compared to a naive semi-classicalanalysis of the Coulomb branch, its quantum structure is highly richer thanexpected due to so-called "dressed" Coulomb branch (monopole) operators. Wepropose dualities and confinement phases for the "chiral" $SU(N)$ theories. Thetheories with $N>F > \bar{F}$ exhibit spontaneous supersymmetry breaking. Thevery many Coulomb branch operators generally remain exactly massless and arenon-trivially mapped under the dualities. Some dualities lead to a novelduality between $SU(N)$ and $USp(2 \tilde{N})$ theories. For the 3d$\mathcal{N}=2$ $SU(2)$ gauge theory with $2F$ doublets, there are generally$F+2$ "chiral" and "non-chiral" dual descriptions.
