The objective of the study was to describe the geographical coverage of Latin American and Caribbean scientific publications on tuberculosis and its international collaboration. The records were retrieved from the PubMed database (2009-2018), limiting the search to Latin American and Caribbean countries. Articles were analyzed in several categories, such as the total number, countries, institutions, authors, collaborations, and citations. The software UCINET and VOSviewer were used. 2,495 items were recovered, 4.2% of world production. More than half of the research came from Brazil (52.5%), Mexico (16.6%) and Peru (10.5%). 97.6% of the production is co-authored, with a rate of international collaboration of 24.5%. The countries with the highest production in international collaboration are Brazil (
