This paper presents 29 sponges of the family Cladorhizidae Dendy, 1922 sampled at 18 different stations in the Weddell Sea, Antarctic during two expeditions of RV Polarstern, PS61 ANT-XIX/2 ANDEEP 2 in 2002 and PS67 ANT-XXII/3 ANDEEP 3 in 2005. Fourteen species from four genera have been registered – one species of Asbestopluma Topsent, 1901, five species of Chondrocladia Thomson, 1873, three species of Cladorhiza Sars, 1872 and five species of Lycopodina Lundbeck, 1905. Six species are endemics of the Southern Ocean. Four species were previously only known from the areas north of the Antarctic and our records of them are thereby new for this region. Two species of Lycopodina, Lycopodina rhabdostylophora sp. nov. and Lycopodina pediculifera sp. nov., are new to science. Our study has considerably expanded the data on diversity of Cladorhizidae in the Southern Ocean. About 27 cladorhizid species (18–19% of global cladorhizid diversity) are now recorded for this region, of which 56% are endemics.
