Important progress has been made in reducing infant and early childhood mortality. However, deaths from external causes are preventable and have a major impact, making them an important public health problem worldwide. This study aims to assess mortality from external causes in children under five in a historical series from 2000 to 2020 in Brazil. This is an ecological study using secondary data from the Mortality Information System, a Ministry of Health system, collected from 2000 to 2020 and analyzed using Joinpoint software to obtain linear regression to correct the rates from junction points in the time series and temporal analysis of the variables. Geoda was used for spatial analysis. The results showed that external causes are among the most prevalent causes of infant mortality and have varied considerably over the time series; in this age group and looking at the groups of causes, it was found that transport accidents are the main cause of death in children under one year of age. When looking at the spatial distribution of mortality from external causes by Urban Articulation Regions, the Boa Vista region showed cluster formation and, consequently, high numbers of deaths from specific causes. With regard to mortality from external causes in children under five, transport accidents represent the most frequent group of external causes; drowning and accidental submersion stand out as the second most frequent in mortality in this age group, and with significant growth in the following years, especially in 2017, with APC = 1.37 in the follow-up from 2015 to 2020, followed by assaults and falls, which showed significant growth in the last two years studied, with APC = 5.09.In relation to the distribution of the mortality rate from external causes in the national territory in the under-age population, there was a trend in the North towards an increase in the mortality rate from external causes, reaching a peak in 2013 of 26 deaths per 100,000 children, although the numbers are gradually reducing, but more slowly than the national scenario.In the Northeast, linear regression shows a downward trend, from a rate of 18.5 to 12.5 between 2000 and 2020. The Southeast and South show a downward trend. In the Midwest, it is possible to see an increase in the mortality rate in the early years of the historical series analyzed, with an APC = 7.29 in the 2000 to 2002 segment, as well as another period of increase between 2011 and 2014, with an APC = 4.56.However, the region managed to maintain a gradual and significant reduction between the periods of rate growth.Thus, it can be concluded that the reduction of preventable deaths in the child population emerges from the implementation of actions whose responsibility falls on the whole of society, aimed at the comprehensive protection of children based on the articulation between the various sectors involved in child protection, such as health, education, social assistance and public safety, so that public policies are more efficient and comprehensive.
