In the context of rigid analytic geometry, a polydisc is a product of discs: the analytic space which is formally dual to the Tate algebra $T_n$ (for an $n$-dimensional polydisk).
This is a basic analytic space. It is the analog in analytic geometry of the affine space $\mathbb{A}^n$ in algebraic geometry.
Those analytic spaces which are subspaces of polydiscs are called affinoids.
Specifically in complex analytic geometry a polydsic is a sub-complex manifold of a product of complex planes
of the form
for $\delta_i \in (0,\infty]$.
e.g. (Maddock, p.6)
Every complex analytic manifold is locally isomorphic to a complex polydisc, in that it may be covered by open subsets which are biholomorphic to complex polydiscs. e.g. (Maddock, p. 7).
In fact (Fornæss-Stout 77a, lemma II.1) states that every connected and second countable complex manifold may already be covered by finitely many open subsets biholomorphic to a polydisc.
See also at good covers by Stein manifolds.
