  This report presents the activities of the `New Physics' working group for
the `Physics at TeV Colliders' workshop (Les Houches, France, 10--28 June,
2019). These activities include studies of direct searches for new physics,
approaches to exploit published data to constrain new physics, as well as the
development of tools to further facilitate these investigations. Benefits of
machine learning for both the search for new physics and the interpretation of
these searches are also presented.
