Luigi "Gigi" Delneri, often incorrectly written as Del Neri (born 23 August 1950) is an Italian football manager, who was last in charge of Udinese.
Born at Aquileia, Udine, Delneri made his professional debut as player at the age of 16 for SPAL, Ferrara's football team, for which he had worked as storer. After playing for Foggia and Novara, he moved to Udinese, with whom he gained promotion to Serie A, Italy's top division. He was later traded to Sampdoria and then to Vicenza, Siena, Pro Gorizia and Opitergina, an amateur team from Oderzo, where he ended his playing career at 34.
After his retirement as a player, Delneri stayed at Oderzo, appointed by chairman Ettore Setten (now owner of Treviso) as head coach. In 1986, he signed for Serie D team Pro Gorizia. He then coached Partinicaudace, a minor Sicilian Serie D team, in 1989, Teramo, Ravenna, Novara and Nocerina of Serie C2; with this last team he won the league and promotion to Serie C1. He then moved to Ternana of Serie C2, guiding it to Serie B after two consecutive promotions.
