数学与物理学中，特别是在微分几何与广义相对论中，扭曲几何（warped geometry）是度规张量可写成如下形式的黎曼流形或劳仑兹流形：

注意到几何可以分解成y几何与x几何的卡氏积（Cartesian product），不过x部份受到扭曲，亦即它的大小尺度受到了一个y座标的纯量函数的调整。基于此理由，扭曲几何的度规常称为「扭曲积度规」（warped product metric）。

扭曲几何很有用处，以其可以运用分离变量法来解与它们有关的偏微分方程序。

In mathematics and physics, in particular differential geometry and general relativity, a warped geometry is a Riemannian or Lorentzian manifold whose metric tensor can be written in form

Note that the geometry almost decomposes into a Cartesian product of the y geometry and the x geometry – except that the x-part is warped, i.e. it is rescaled by a scalar function of the other coordinates y. For this reason, the metric of a warped geometry is often called a warped product metric.
