Quinuclidine is an organic compound and a bicyclic amine and used as a catalyst and a chemical building block. It is a strong base with pKa of the conjugate acid of 11.0.^[2] This is due to greater availability of the nitrogen lone pair^{[citation needed]}. It can be prepared by reduction of quinuclidone.

The compound is structurally related to DABCO in which the other bridgehead is also nitrogen and tropane with a slightly different carbon frame.

Quinuclidine is found as a structural component of some biomolecules including quinine.
