The cultivation of chili peppers (Capsicum spp.) in Burkina Faso has become an important occupation and a great source of incomes, helping farmers to fight against poverty. However, local cultivars have low yields, essentially because of the pest pressure and the limited access to improved seeds. This study aims to contribute to a better knowledge of its diversity to lay the basis of its improvement. Thus, fifty-nine (59) accessions were characterized according to RCBD design with three (03) repetitions using 12 qualitative variables and 12 quantitative variables. The study showed great diversity within the accessions studied. The qualitative variables were all discriminate the accessions, except colour of the seed. Interesting and significant correlations between several characteristics, especially between leaf and fruit parameters were also revealed. A structuring of the accessions in 3 composite clusters reflecting the higher intra-accession diversity was observed. These results provide a basis for future selection and valorization works of chili pepper in Burkina Faso
