Kakhi Kakhiashvili (Georgian: კახი კახიაშვილი, Greek: Ακάκιος "Κάχι" Κακιασβίλης; born 13 July 1969 in Tskhinvali, Georgian SSR, USSR) is a Georgian-Greek weightlifter, one of only six weightlifters to have won three consecutive gold medals at Olympic Games.

He won his first at Barcelona 1992, competing with the Unified Team, and later as a citizen of Greece at Atlanta 1996 and in Sydney 2000.

Kakhiashvili was born in Tskhinvali, Georgia, to a Georgian father and a Greek mother, Maria Lamprianidi.

At the 1992 Summer Olympics lifting for the Unified Team in the 90 kg category, he went against the instructions of his coach Vasily Alexeev, the all-time weightlifting great.

Event though his total tied Syrstov, Kakhiashvili won the gold medal due to virtue of a lighter bodyweight,[4] (89.25 kg vs. 89.45 kg) this performance established his right to the title of one of the sports elite lifters.
