Slavomír Knazovický (born 3 May 1967 in Pieštany) is a Czechoslovak-Slovak sprint canoer who competed from the early 1990s to the early 2000s (decade).
Competing in three Summer Olympics, he won a silver in the C-1 500 m event at Atlanta in 1996.
An out-and-out sprinter, his preferred distance was in fact the 200 m (not included on the Olympic schedule).
In 1997 he became European C-1 200 m champion in Plovdiv, Bulgaria.
The following year he won the silver medal in Szeged, Hungary.
In 1999 he was a bronze medallist at both the World and European Championships.
Knazovický also earned a bronze in the C-4 500 m event at the 1994 World championships in Mexico City.
Knazovický is now the coach of the current Slovakian number one Marián Ostrcil.
