In 1934, H. Whitney gave a necessary and sufficient condition on a jet of order $m$ on a closed subset of $E$ of $\mathbb R^n$ to be the jet of order $m$ of a $C^m$-function. Later, K. Kurdyka and W. Pawłucki proposed a subanalytic version of this theorem. In this paper, we work in an o-minimal expansion of a real closed field and prove a definable version of Whitney’s Extension Theorem.
