We will describe the appearance of certain algebraic structures in

the kinematic dependence of scattering amplitudes, both in gauge

theory and in gravity. These structures mirror the colour dependence

of the amplitude in the case of gauge theory, making the so-called

colour/kinematics duality manifest. We will mainly focus on the

kinematic algebras arising from the recently proposed scattering

equations, which give a decomposition of the amplitude into simpler

building blocks. We will also briefly discuss a different realisation of

the kinematic algebra, inspired by the geometry of Lie groups.
