- Western Bolivian Guaraní (AKA Simba), 7,000 speakers
- Eastern Bolivian Guaraní (AKA Chiriguano, Chawuncu, Western Argentine Guaraní), 55,000 speakers
- dialects: Avá (subdialects Chané, Tapieté AKA Ñandeva), Izoceño/Izocenio
- Paraguayan Guaraní (Guarani proper), 5 million mostly mestizo speakers
- Chiripá Guaraní (AKA Avá, Nhandéva/Ñandeva, Apytare, Tsiripá/Txiripá), 12,000 speakers
- Mbyá Guaraní (Mbya), 25,000 speakers
These share some degree of mutual intelligibility and are close to being dialects; however, Chiripá is reported to be intelligible due to bilingualism, not inherently. Also, there is a degree of intelligibility with Kaiwá–Pai Tavytera, which is not included in the by Ethnologue. Ethnologue considers Tapieté to be a separate language, intermediate between Eastern Bolivian and Paraguayan, and has shifted from the name Chiripá to Avá, though the latter is ambiguous. Paraguayan Guaraní is by far the most widely spoken variety and is what is often meant by the term 'Guaraní' outside South America.
Distribution of Guaraní 
Paraguayan Guaraní, is, alongside Spanish, one of the official languages of Paraguay. Paraguay's constitution is bilingual, and its state-produced textbooks are typically half in Spanish and half in Guaraní.
Speakers of Guaraní who are not fluent in any other language have markedly limited opportunities for education and employment.There are very few speakers of Guaraní outside South America. Those few that exist include emigrants, scholars, missionaries, and former volunteers of the Peace Corps.
A variety of Guaraní known as Chiripá is also spoken in Paraguay. It is closely related to Paraguayan Guaraní, a language which speakers are increasingly switching to. There are 7,000 speakers of Chiripá in Paraguay.
A different variety of Guarani, Western Argentine Guaraní, is spoken further west by about 15,000 speakers, mostly in Jujuy, but also in Salta Province. It refers essentially to the same variety of Guaraní as Eastern Bolivian Guaraní.
Additionally, another variety of Guaraní known as Mbyá is spoken in Argentina by 3,000 speakers.
Eastern Bolivian Guaraní, also known as Chawuncu or Chiriguano, is spoken in by 33,670 speakers (or 36,917) in the south-central Parapeti River area and in the city of Tarija. It refers to essentially the same variety of Guaraní as Western Argentine Guaraní.
In August 2009 Bolivia launched a Guarani-language university at Kuruyuki in the southeastern province of Chuquisaca which will bear the name of indigenous hero Apiaguaiki Tumpa.
Paraguayan Guaraní, together with its Tupian sisters, the língua geral paulista (presently extinct) and the língua geral amazônica (whose modern descendant is Nheengatu), was once as prevalent in Brazil as it is in Paraguay. The language began a long period of decline in Brazil when the Jesuits, who had done much to spread and standardize it, were expelled from the Portuguese Empire by order of the Portuguese prime minister Marquis of Pombal in 1759. Guaraní survives in scattered pockets throughout Brazil, one of which can be found in a rural district within the municipality of São Paulo. Olívio Jekupé, a resident of Krukutu village, located in this area, has published a book of folk tales written in Guaraní and Portuguese. Because of its proximity with Paraguay, in Mato Grosso do Sul (Ponta Porã), the Guaraní language is a second language locally. In 2010, Guaraní gained the status of official language alongside Portuguese in the municipality of Tacuru, Mato Grosso do Sul. In Brazil, Paraguayan Guaraní is generally referred to as Guarani-Kaiowá.
The variety of Guaraní known as Chiripá is also spoken in Brazil by 4,900 speakers. Chiripá is called Nhandeva in Brazil. Its speakers are increasingly switching to Paraguayan Guaraní.
Additionally, Mbyá Guaraní is spoken in Brazil by 16,050 speakers.
