Luca Grimaldi

Luca Grimaldi (early 13th century – 18 April 1275) was a Genoese nobleman and diplomat of the Guelph party, son of Ingo Grimaldi. First recorded in 1239 in Genoa's alliance with Milan against Emperor Frederick II, he and his brother Boarello took control of the castles of Stella and Andora after the Savona revolt of 1248–1251.

He was podestà of Florence in 1257 and Genoese ambassador to Pope Alexander IV in 1258. When the Ghibellines under Oberto Doria and Oberto Spinola took Genoa in 1271, he was exiled to Stella and died in 1275.
