The centre of the Milky Way harbours a Nuclear Stellar Disc (NSD), a highly flattened and dense stellar structure that dominates the gravitational field at Galactocentric radius 30<R<300 pc. Dynamical models are key to understand the structure and formation of this poorly understood component of our Galaxy. Only recently it has become possible to construct dynamical models of NSD thanks to high angular resolution astrometric and spectroscopic infrared datasets that can pierce through the extreme extinction that characterises the Galactic centre. In this talk I will give an introduction to the NSD and I will present the first fully self-consistent 6D (position+velocity) dynamical models of the NSD.
