Theodoros Modis (Greek: Θεόδωρος Μόδης) was a Greek lumber merchant and scholar from Monastiri (today's Bitola, in North Macedonia).
[1][2] He was among those who helped the founders of the Revolutionary Internal Organization in its formation, in order to defend Greek interests in Macedonia (Ottoman Empire at the time.).
[3] He was assassinated in his shop by Bulgarian komitadji on September 4, 1904.
His assassination, like the killing of Pavlos Melas a month later, is among the violent events that marked the beginning of the Macedonian Struggle (Μακεδονικός Αγώνας in Greek).
[4] He is the grandfather of Theodore Modis, the great-grandfather of Yorgo Modis, and the uncle of Georgios Modis.
