We present the complete integrands of five-point superamplitudes in N=4super-Yang-Mills theory and N=8 supergravity, at one and two loops, forfour-dimensional external states and D-dimensional internal kinematics. For N=4super-Yang-Mills theory we give the amplitudes for general gauge group --including all non-planar contributions. The results are constructed usingintegral diagrams that manifestly satisfy the conjectured duality between colorand kinematics, providing additional nontrivial evidence in favor of theduality for multipoint and multiloop amplitudes. We determine the ultravioletpoles by integrating the amplitudes in the dimensions where logarithmicdivergences first occur. We introduce new kinematic prefactors which offer aconvenient decomposition of the external state structure of the nonplanarfive-point amplitudes in the maximally supersymmetric theories to all looporders.
