    This research project seeks to identify the companies with the highest market concentration in the tanning and dressing sector in Ecuador, to describe the behavior of the profitability indicators of the four most representative companies in the sector and to interpret the relationship between the market concentration and the profitability of the oligopoly registered in the sector. The study is carried out through the structuring of five linear regression econometric models, which analyze the relationship between oligopoly profitability and market concentration, GDP growth rate and production costs. According to this, tests of suitability of the models such as the Ramsey RESET test, the nonlinearity test and the Collinearity test were carried out using the Inflation Factor of Variance. The investigation concluded that the leather tanning and marinating sector is concentrated and exerts market power, identifying an oligopoly formed by the companies: Curtiduría Tungurahua S.A., Servicueros S.A., Curtiembre Renaciente S.A. And Tenería San José.
