The WLCG/HSF Workshop 2025 brings together the Worldwide LHC Computing Grid (WLCG) and the HEP Software Foundation (HSF) communities to discuss key technical and strategic topics shaping the future of computing and software for high-energy physics. With the challenges of HL-LHC approaching, this workshop serves as a platform to exchange ideas, review ongoing developments, and coordinate efforts across our partially overlapping communities.

Several important themes will be explored, spanning WLCG Technical evolution, operations, software innovation, and long-term sustainability, all with the ultimate goal of ensuring that LHC ambitious physics program is fully enabled by cutting-edge computing infrastructure and software solutions.
