Extended (N≥4) superconformal Chern-Simons-matter (CSM) theories in 3D are natural candidates of the dual gauge theories of multi M2-branes, which are fundamental objects in M-theory. In the literature, the N=4,5,6 CSM theories were constructed by using ordinary Lie 2-algebras, and the N=8 theory was constructed by using Nambu 3-algebra. We introduce the notion of symplectic 3-algebra, and construct all N≥4 CSM theories in terms of this unified 3-algebraic structure. Using superalgebras to realize the 3-algebras, we recover all known examples of the  N≥4 CMS theories, and derive some new N=4 quiver gauge theories as well.
