Republicanism in Australia is a movement to change Australia's system of government from a constitutional parliamentary monarchy to a republic, removing the power of the monarch of Australia. Republicanism was first espoused in Australia before Federation in 1901. After a period of decline after Federation, the movement again became prominent at the end of the 20th century after successive legal and socio-cultural changes loosened Australia's ties with the United Kingdom.

Canadian republicanism is a movement among Canadians for the replacement of the Canadian system of federal constitutional monarchy with a republican form of government. These beliefs are expressed either individually—usually in academic circles—or through the country's one republican lobby group. Republicans have no preferred model of republic, as individuals are driven by various factors, such as a perceived practicality of popular power being placed in the hands of an elected prime Minister or a different manifestation of the modern nation. As with its political counterpart, strong republicanism is not a prevalent element of contemporary Canadian society. The movement's roots precede Canadian Confederation and it has emerged from time to time in Canadian politics, but has not been a dominant force since the Rebellions of 1837, of which Canadian republicans consider their efforts to be a continuation.

Morocco, currently a monarchy, has known some attempts to establish republican forms of government. Some of those attempts are continuing to this day:Morisco refugees from Andalusia formed in Salé and Rabat the Republic of Bou Regreg, a base for piracy (1627-1668). Berber rebels in the Rif Region first established the Rif Republic (1921-1926) under Abd el-Krim against Spanish colonial rule, the state lasted until 1925 when the rebels tried to take the city of Fes, in a failed attempt to expand the republic into French Morocco. In 1971 army cadets under General Madbouh and Colonel Ababuh attacked king Hassan II in the Shkirat palace. A republic was proclaimed on Radio Rabat, was but suppressed by General Mohamed Oufkir. However, in 1972 Oufkir initiated his own coup d'état; the Air Force tried multiple times to bring down the king's airplane, attacked the Rabat airport and bombed the royal palace in Rabat. The coup ultimately failed. During the 2011–2012 Moroccan protests, a few protesters chanted republican slogans. They were mainly from the Al Adl Wa Al Ihssane Islamist movement, the Ila al-Amam marxist group and some leftist streams. These slogans weren't repeated by the vast majority of the protesters.
