This Paper is a clear attempt to analyze the efforts that done towards informal settlements in Egypt in the years with emphasis on the role of the public participation on the planning process. The aim of this paper is to map the dimensions of successful participation especially after the uprising of 25th of January revolution, the perception of participation must be different and deeper now, as in some previous cases; participation process was not completely transparent with the public, and in some cases the participation was limited or excluded to certain people or representative that worked with the government and doesn't represent the sound of local residents of informal areas. This will happen through studying and analyzing some cases of upgrading informal areas in Egypt and analyze its negative and positive points.
