I will first discuss some basic features of non-relativistic gravity of which Newton- Cartan gravity, the frame independent reformulation of Newtonian gravity, is the most prominent example. In particular, I will discuss an application of the so-called Lie algebra expansion method to construct actions for a number of non-relativistic gravity theories that have appeared in the recent literature. After that I will identify the non-relativistic geometry underlying non-relativistic string theory and discuss some basic properties of non-relativistic string theory such as the quantum consistency and T-duality.
