It is our great pleasure to welcome you to the 22nd ACM SIGPLAN Erlang Workshop (Erlang’23), co-located as usual with the annual International Conference on Functional Programming (ICFP), held in Seattle, Washington, United States. The workshop continues to be a forum for presenting research and experience reports on all aspects of theory, implementation, and applications of the Erlang language and BEAM-related technologies, covering topics in functional programming, concurrency, distribution, and reliability.@en
