Luca George Prodan (17 May 1953 – 22 December 1987) was an Italian–Scottish musician and singer, best known as lead vocalist of the influential Argentine alternative rock band Sumo. He is widely considered one of the country's most important artists.

Born in Rome to an affluent family in the art industry, Prodan was sent at nine years old to the United Kingdom for school at Gordonstoun. During his studies, Prodan learned to play the guitar and became heavily influenced by the recent progressive and psychedelic rock music that have emerged during the decade. At seventeen years old and one year away from graduating, Prodan abandoned his studies and returned to Italy. Prodan eventually returned to the United Kingdom for work, settling across Brighton, Manchester, and London; he soon became addicted to heroin.

Prodan moved to the outskirts of Buenos Aires in 1980 to recover from his heroin addiction, where he met Germán Daffunchio (brother-in-law of Prodan's friend from Gordonstoun, Timmy McKern) and Alejandro Sokol. Together they formed Sumo. For much of the decade until Prodan's death, the band would become one of the most influential groups in shaping Argentine rock of its time. Prodan, along with the rest of Sumo, are credited for introducing British post-punk to not just Argentina, but to the continent, by providing songs in the English language, and for providing a visceral counterpoint to the progressive-influenced themes that dominated Spanish-language rock at that time.

Prodan was the older brother of Italian film actor and composer, Andrea Prodan.

Luca George Prodan was born in Rome on 17 May 1953, the son of Mario Prodan, an Italian citizen born in the Austro-Hungarian Empire, and Cecilia Pollock, born in China to Scottish parents who worked between Shanghai and Beijing before World War II. His father had set up a prosperous business in ancient Chinese ceramics that became untenable after the Japanese invasion of China during the war.

Prodan was the third child of four: Michela (Michaela) and Claudia were the oldest, and Andrea was the youngest. Michela and Andrea worked in the world of cinema, although Andrea has a musical background as a soloist with England's most famous choir in his early youth and as a creative musician in his later years.

In 1962, when Prodan was nine years old, his parents sent him to Britain to the prestigious Gordonstoun School, the same school attended by King Charles III. An urban legend in Argentina is that Prodan once hit Charles III, although the monarch is five years older. During his academic studies, Prodan befriended Timmy McKern, a Scottish Argentine, who would be his friend until his death. In 1970, at seventeen years old and just one year shy of completing his studies, Prodan dropped out and fled from Gordonstoun. As his family requested his search through the Interpol, Prodan was travelling across Europe alone back to Rome. Prodan sold a shotgun beforehand to fund his trip. He was eventually found by his mother in Rome while being arrested by the police.

Later in his life, Prodan got a job at a newly established Virgin Records store in Marble Arch, London. During his tenure with the store, Prodan began to accumulate some of the most famous records – most of which were stolen from a warehouse – in which one in every 10 records he sold would end up in his house. He was quickly fired, but was soon rehired at the expense of clients who claimed Prodan was "the Italian who could discover the title of a song and its interpreter just by listening to an out of tune whistle." Nonetheless, Prodan's second chance at Virgin Records was short-lived; Prodan continued to steal records, and his theft record reached levels of excess. In addition to taking records for his personal gain, he also stole records for his friends and his brother Andrea.
