  In this work we propose the geometric mean of bipartite concurrences as a
genuine multipartite entanglement measure. This measure achieves the maximum
value for absolutely maximally entangled states and has desirable properties
for quantifying potential quantum resources. The simplicity and symmetry in the
definition facilitates its computation for various multipartite entangled
states including the GHZ states and the $W$ states. With explicit examples we
show that our measure results in distinct entanglement orderings from other
measures, and can detect differences in certain types of genuine multipartite
entanglement while other measures cannot. These results justify the practical
application of our measure for tasks involving genuine multipartite
entanglement.
