Objective:The species of Ipomoea and the Convolvulus, which  belong to Convolvulaceae, are invasive weeds and commonly found in the world as a annual or perennial. Surveys were conducted in the Mediterranean Region to determine the extensity and density of Ipomoea and Convolvulus species, which stand out with their invasive characteristics, and are problematic for many cultivated plants. Material and Methods: Surveys has been done in  Antalya, Adana, Mersin, Hatay, Kahramanmaraş and Osmaniye provinces in the Mediterranean region and each provincial center was accepted as the beginning. During the surveys, every 10 km was randomly stopped and samples were taken from an area of 1 da to represent the agricultural area. Weeds were counted 5 times randomly from each frame of 1 m2. Results: According to results of survey, totally 8 8 weed species belonging to Convolvulaceae family have been identified in the Mediterranean Region, 5 of thembelongs to the genus Convolvulus and 3 of them belongs to the genus Ipomoea. Their types, frequency (%) and density (plant/m2) were given respectively Convolvulus arvensis L. (52.32 and 0.57), Convolvulus scammonia L. (0.86 and> 0.01), Convolvulus stachydifolius Coisy (0.69 and 0.01), Convolvulus betonicifolius Mill. (0.52 ve> 0.01), Convolvulus galaticus Roston. ex Choisy (0.17 and> 0.01), Ipomoea triloba L. (9.12 and 0.13), Ipomoea hederacea (Linn) Jacq. (3.44 and 0.02) and Ipomoea purpurea (L.) Roth. (1.20 and 0.01).
