The work was carried out with the objective of updating the weed flora associated with sugar cane in Cuba. Weed identification surveys corresponding to 2023 were carried out in all sugarcane production units in the country. Identification was carried out by walking the field along its diagonals, with the help of catalogs to the identification of the species. Families' diversity index, the relative frequency of the species at the field and the relation of interference for morfotipo they were determinated. The frequency was determined and classified into the categories of: Accidental; Uncommon; Moderately common and Very common. The surveys showed the existence of seven families, of which two belong to the class Liliatae (Monocotyledons) and five to the Magnoliatae (Dicotyledons). The Poaceae family presented the highest relative diversity index (54.2%), followed by Fabaceae and Mimosaceae with the same value (12.5%). twenty one genera were distinguished, 11 from the class Liliatae and 10 from the Magnoliatae. The most frequent were Brachiaria and Sorghum, both from the Poaceae family, with three and two meanings, respectively. The floristic inventory revealed the existence of 24 species of weeds associated with sugar cane as the most frequent at the national level, with frequency values above 1%, of which 14 belong to the class Liliatae and 10 to the Magnoliatae.
