This paper explained what the crime of usurpation is in the criminal legal system of the Republic of Panama. It started with an analysis of the Panamanian and international criminal theory, as well as a hermeneutical study of the Criminal Code against its different modalities (exegetical method of interpretation). An explanation about the legal interest, the material object of the crime and the penalty was made. A criminal decision of the Panamanian Administration of Justice regarding the usurpation was also studied. For this, techniques were used to review Panamanian normative sources, jurisprudence analysis and bibliographic review -mainly Panamanian-. In it, it was concluded, among others, that the crime of usurpation consists of the seizure of someone else's real estate by changing the limits of the property or through actions with a social disvalue such as violence or deception.
