The ML Workshop is an annual workshop organized in affiliation with the International Conference on Functional Programming ICFP). The workshop is sponsored by the Association for Computing Machinery (ACM) under the aegis of the ACM Special Interest Group on Programming Languages (SIGPLAN).

ML is a family of programming languages that includes dialects known as Standard ML, Objective Caml, and F#. The development of these languages has inspired a large amount of computer science research, both practical and theoretical. This workshop aims to build on previous occasions (recent instances are 2009 in Edinburgh, 2010 in Baltimore, and 2011 in Tokyo), providing a forum to encourage discussion and research on ML and related technology. The scope of the workshop includes all aspects of the design, semantics, theory, application, implementation, and teaching of members of the ML family.
