Introduction: Cancer is a disease that affects a large number of people worldwide and generates a high mortality rate. Oral and oropharyngeal cancer is considered a public health problem, especially in low- and middle-income countries. By the year 2023, it is estimated that 11,580 people will die in the United States from this cause. Objective: Determine the variation in mortality from oral and oropharyngeal cancer in Chile between 1955 and 2021. Methods: The mortality data was obtained from institutions such as the National Institute of Statistics and the Chile Ministry of Health through the country's death registries, which were classified by gender. Crude mortality rates for each year of the study were calculated from the institutions' mortality data and population data. Results: Crude mortality rates between study years ranged from 0.92 to 1.53. men obtained an average rate of 1.64 per 100,000 inhabitants, and women obtained an average rate of 0.67 per 100,000 inhabitants. Conclusion: The crude mortality rate from oral and oropharyngeal cancer in Chile increased between 1955 and 2021 in both men and women.
