Toccata is a research team of the INRIA Saclay - Île-de-France research center, joint with LRI (CNRS and University of Paris-Sud), located in Orsay, France. It was created in September 2012, partly as a refoundation of the former team ProVal.

The general objective of the team is to promote formal specification and computer-assisted proof in the development of software that requires a high assurance of its safety and its correctness with respect to its intended behavior.
