Under the Brazilian military government
During the Brazilian military government from 1964 to 1985, terrorism was a term frequently used by the state. All forms of opposition to the military regime were considered forms of terrorism; opposition members were deemed "terrorists."

Some groups engaged in urban guerrilla attacks against the regime; in a 1969 panflet ALN members described themselves as ''' Guerrillas, terrorists and robbers; not men who depend on votes from other revolutionaries or whoeve to fulfill their duty to make the revolution. ''

An incident of right-wing terrorism known as the Riocentro attack occurred in 1981, perpetrated by a sector of the military dissatisfied with the democratic opening of the regime.

Recent history
On 21 July 2016, two weeks before the scheduled start of the Olympic Games, Brazilian Federal Police busted an Islamic jihadist terrorist ring plotting to wreak havoc in a manner similar to the 1972 Munich massacre, but they had a rather poor preparation compared to their objectives. 10 people suspected to be allied with ISIS were arrested and two more were on the run.

On 2 May 2017, Palestinian migrants threw a homemade bomb at far-right protesters, leaving several injured in São Paulo.

On 6 September 2018, the right-wing presidential candidate Jair Bolsonaro was stabbed during a political campaign in Juiz de Fora, Minas Gerais.

On 13 March 2019, two former students opened fire at a Brazilian school in Suzano, São Paulo.

On 8 November 2023, the Federal Police of Brazil arrested 2 men and carried out 11 search and seizure warrants, in the states of São Paulo, Minas Gerais and Brasília, in an operation against the terrorist group Hezbollah, which was planning attacks on synagogues in the country.

Several newspapers, including O Globo, Veja, and Folha de S.Paulo, characterised the 2023 invasion of the Brazilian Congress as terrorism.

Responses and counterterrorism efforts
The Brazil government has four pieces of terrorism legislation pending in Congress:

 * Terrorism during the World Cup – in 2011, legislation was introduced that deals with specific crimes, including terrorism, during and preceding the World Cup;
 * Penal code update – legislation in 2012 sought to update the Brazilian penal code to include sentencing guidelines for terrorism crimes;
 * Terrorism definitions – legislation in 2013 sought to define terrorism under the Brazilian Constitution.

Criticism
There is a large concentration of Middle Eastern immigrants in the area near the Paraguay, Argentina, Brazil border. Some authorities monitoring the area have stated that Brazil should participate more in the international fight against terrorism.
