Euclid is a class-M space mission by ESA launched in July 2023. In the course of its six years lifetime, it will observ ~14,000 sq. degrees of the extragalactic sky with the aim of understanding the nature of dark matter and dark energy combining multiple cosmological probes such as weak lensing and galaxy clusters. Being designed for accurate shape measurements from space and having a space resolution not far for HST, Euclid is also a very powerful telescope to find and study strong gravitational lenses on galaxy and galaxy cluster scales. In this talk, I will briefly summarize the work done by the Strong Lensing Working Group of the Euclid Consortium to compile the first catalogs of strong lensing with the Q1 data release. In particular, I will focus on galaxy clusters. I will show that Euclid will enable us to address open questions such as the excess of galaxy-galaxy strong lensing events reported in galaxy clusters also using a statistical approach, thanks to the large number of lenses it will discover.
