Werner Schlager (born September 28, 1972 in Wiener Neustadt, Austria) is a table tennis player and former world champion from Austria.
 Schlager began playing table tennis when he was six years old, learning from his father, Rudolph Schlager and brother, Harald Schlager who were also top Austrian players, making them ideal training partners. In fact, starting out, Schlager became well-versed playing both with and against long pips like his brother. After placing top in numerous singles and doubles tournaments, he won the 2003 Singles World Championship held in Paris beating South Korean Joo Se-Hyuk in the final to clinch the world title.
 Werner Schlager was renowned for his immense skill in service and receive, which was one of the biggest contributors to his success. His serves were  patently legal, and relied solely on creativity rather than trying to hide the ball. His serving has been admired and praised by the likes of Liu Guoliang. In an interview, after being asked about how he creates his serves, he responded ''I dream about them''. He was also very well known for having a magnificent third ball attack that worked in unison with his serves. His style is very aggressive and fast, as he plays many blocks and counter-hits, as opposed to slower strokes. He had a very good forehand and backhand. He was respected by the Chinese players for his incredible serve and third ball, which they were wary of. He is also well known for being a very tactical and intellectual player. Coupled with a brave and enthusiastic spirit, he has caused many upsets and comebacks over the years.
 In the quarter-final of the 2003 World Table Tennis Championships, he came up against one of the top seeds in the tournament and former world champion; Wang Liqin. After being 3-1 down in games, he evened it up at 3–2, and then proceeded to save 4 match points at 6-10 down. He took that game 13–11. With the games at 3-3, Werner Schlager took game 7 convincingly at 11-5 and progressed onto the semi-finals. He then faced Kong Linghui, and managed to save a match point at 12–11 in the final game. He then took the game 14-12 and consequently the match. In the final, he played against South Korean chopper, Joo Sae-hyuk, which he won quite convincingly at 4–2. He said this win was attributed to the fact that he has had a lot of experience against this kind of style, as he constantly played with Chen Weixing, a fellow Austrian national team member. When asked about his surprising performance, Schlager commented, "I can tell you the secret for my World Championship title in the year 2003...I was in love and you know and this is also opens many many doors and makes many things possible."
 He therefore is the first Austrian since Richard Bergmann in 1937 to win the World Championship Singles.
That year, he was voted Austrian Sportsman of the Year and selected in China as "The most popular foreign sportsman".
 In 2009, he founded the Werner Schlager Academy in Schwechat close to Vienna, a training centre which is also home to clubs SVS Niederösterreich and SVS Ströck.  Schlager published his book in 2011, Table Tennis: Tips from a World Champion.
