Ľubomír Ftáčnik (born October 30, 1957, in Bratislava) is a Slovak chess grandmaster and a former European Junior Champion.

At Cienfuegos (Capablanca Memorial) 1980, Dortmund GM 1981 and Lugano Open 1988, he shared first place, and at Hradec Králové in 1981 he was runner-up.

His major triumph occurred in 1982, when a 67.9% score helped the Czechoslovaks win the silver medal, very much against expectation.

In the US he has attended chess summer camps, promoted his book (Winning The Won Game - 2004 Batsford/Chrysalis, co-authored with Danny Kopec) and played in tournaments.

He also played the Amsterdam 2006 event and finished a creditable half point off the leaders in what was a very strong field (Tiviakov, Timman, Nijboer, Tukmakov among others).
