  We present the complete integrands of five-point superamplitudes in N=4
super-Yang-Mills theory and N=8 supergravity, at one and two loops, for
four-dimensional external states and D-dimensional internal kinematics. For N=4
super-Yang-Mills theory we give the amplitudes for general gauge group --
including all non-planar contributions. The results are constructed using
integral diagrams that manifestly satisfy the conjectured duality between color
and kinematics, providing additional nontrivial evidence in favor of the
duality for multipoint and multiloop amplitudes. We determine the ultraviolet
poles by integrating the amplitudes in the dimensions where logarithmic
divergences first occur. We introduce new kinematic prefactors which offer a
convenient decomposition of the external state structure of the nonplanar
five-point amplitudes in the maximally supersymmetric theories to all loop
orders.
