The International Conference on Interactive Theorem Proving (ITP 2026) will take place on 26-29 July, 2026 in Lisbon, Portugal, as part of FLoC'26. ITP 2026 is part of the ITP conference series whose history goes back to 1988.

ITP welcomes submissions describing original research on all aspects of interactive theorem proving and its applications. Suggested topics include, but are not limited to, the following:

formalizations of computational models
improvements in interactive theorem prover technology
formalizations of mathematics
integration with automated provers and other symbolic tools
verification of security algorithms
industrial applications of interactive theorem provers
formal specification and verification of hardware and software
user interfaces for interactive theorem provers
use of theorem provers in education
concise and elegant worked examples of formalizations (proof pearls)
