  We describe K-mouflage models of modified gravity using the effective field
theory of dark energy. We show how the Lagrangian density $K$ defining the
K-mouflage models appears in the effective field theory framework, at both the
exact fully nonlinear level and at the quadratic order of the effective action.
We find that K-mouflage scenarios only generate the operator $(\delta
g^{00}_{(u)})^n$ at each order $n$. We also reverse engineer K-mouflage models
by reconstructing the whole effective field theory, and the full cosmological
behaviour, from two functions of the Jordan-frame scale factor in a tomographic
manner. This parameterisation is directly related to the implementation of the
K-mouflage screening mechanism: screening occurs when $ K'$ is large in a dense
environment such as the deep matter and radiation eras. In this way, K-mouflage
can be easily implemented as a calculable subclass of models described by the
effective field theory of dark energy which could be probed by future surveys.
