This volume contains the post-proceedings of PLACES 2014, the seventh Workshop on Programming Language Approaches to Concurrency and Communication-cEntric Software, which was held in Grenoble, France, on April 12th 2014, and co-located with ETAPS, the European Joint Conferences on Theory and Practice of Software. The PLACES workshop series aims to offer a forum where researchers from different fields exchange new ideas on one of the central challenges for programming in the near future: the development of programming languages, methodologies and infrastructures where concurrency and distribution are the norm rather than a marginal concern. Previous editions of PLACES were held in Rome (2013), Tallin (2012), Saarbrueken (2011), Paphos (2010) and York (2009), all co-located with ETAPS, and the first PLACES was held in Oslo and co-located with DisCoTec (2008). The Program Committee, after a careful and thorough reviewing process, selected nine papers out of 12 submissions for presentation at the workshop and inclusion in this post-proceedings. Each submission was evaluated by three referees (with one paper receiving a fourth review), and the accepted papers were selected during a week-long electronic discussion. One of the nine accepted papers was conditionally accepted subject to a process of shepherding by a PC member, which was successful and led to the paper's full acceptance. In addition to the contributed papers, the workshop will feature an invited talk by Akash Lal, Microsoft Research India, entitled "Finding Concurrency Bugs Under Imprecise Harnesses".
