Giuseppina Pasqualino di Marineo (9 December 1974 – 31 March 2008), known as Pippa Bacca, was an Italian performance and feminist artist. On 31 March 2008, Pippa Bacca disappeared in Gebze in Turkey during an international hitchhiking trip to promote world peace under the motto, "marriage between different peoples and nations". Bacca and fellow artist Silvia Moro were symbolically wearing a wedding dress during their trek. On 11 April 2008 the police arrested a man who later confessed to her murder and led the authorities to the discovery of her body.
