Climbers are highly represented in tropical forests and are of great ecological importance, having been identified as one of the key factors that differentiate tropical forests from temperate rainforests. This paper presents the climber species of the Caiua Ecological Station (EECAIUA) in the City of Diamante do Norte, Parana State; the Station is located in a submountainous seasonal semideciduous forest (SSF) and is situated on the edge of the Paranapanema river. We found 17 families, 44 genera and 53 species of vines. The five families with the greatest number of species jointly accounted for 57% of the total species found. Herbaceous vines occurred less frequently than did lianas. When considering the climbing strategy used by the species, the graspers were the most diverse, followed by those that had tendrils (scramblers) and climbers. An identification key based on vegetative characters of families found in other parts of northern Parana was created for the families of this location. Keywords: Diamante do Norte, seasonal deciduous forest, liana. As trepadeiras sao plantas com alta representatividade nas florestas tropicais e de grande importancia ecologica, apontadas como um dos fatores basicos que diferencia florestas tropicais de temperadas. Este trabalho apresenta as especies de trepadeiras da Estacao Ecologica do Caiua (EECAIUA), municipio de Diamante do Norte, Estado do Parana, inserida na floresta estacional semidecidual (FES) submontana, situada a margem do rio Paranapanema. Foram encontradas 17 familias, 44 generos e 53 especies. As cinco familias mais ricas em numero de especies perfazem juntas 57% do total encontrado. As trepadeiras herbaceas ocorrem em menor numero quando comparadas as lianas, e quanto a estrategia utilizada para ascender, as voluveis sao as mais diversas, seguidas pelas de orgaos preensores (gavinhas) e escandentes. Uma chave de identificacao para familias, baseada em caracteres vegetativos, foi produzida para as familias desta localidade com as familias encontradas em outras duas no Norte do Parana. Palavras-chave: Diamante do Norte, floresta estacional semidecidual, liana.
