This volume contains the proceedings of the 7th International Symposium on Functional and Logic Programming (FLOPS 2004), held in Nara, Japan, April 7¿9, 2004 at the New Public Hall, Nara. FLOPS is a forum for research on all issues concerning functional progr- mingandlogicprogramming. Inparticularitaimstostimulatethecross-fertili- tion as well as the integration of the two paradigms. The previous FLOPS me- ings took place in Fuji-Susono (1995), Shonan (1996), Kyoto (1998), Tsukuba (1999),Tokyo(2001)and Aizu (2002). The proceedingsofFLOPS 1999,FLOPS 2001 and FLOPS 2002 were published by Springer-Verlag in the Lecture Notes in Computer Science series, as volumes 1722, 2024 and 2441, respectively. In response to the call for papers, 55 papers were submitted by authors from 1 Australia (1), Austria (1), Canada (1), China (4), Denmark (2), Estonia ( ), 2 1 1 France (3 ), Germany (4 ), Italy (1), Japan (15), the Netherlands (1), Oman 2 4 1 1 (1), Portugal ( ), Singapore (2), Spain (8), UK (3), and USA (6 ).

The program committee meeting was conducted el- tronically for a period of 2 weeks in December 2003. After careful and thorough discussion, the program committee selected 18 papers (33%) for presentation at theconference.
