Aleš Kotalík (born 23 December 1978) is a professional ice hockey right winger playing for the Calgary Flames of the National Hockey League.
Kotalík was drafted 164th overall by the Buffalo Sabres in the 1998 NHL Entry Draft. In the 2005–06 NHL season, he had a career high in goals 25, assists 37 and points 62. The recent 2006–07 NHL season he was 5 for 7 in shootouts and second in the NHL with four shootout deciding goals. He was out for 16 games because of an injured right knee.
On March 4, 2009, Kotalík was traded by the Sabres to the Edmonton Oilers in exchange for a 2nd round pick in the 2009 NHL Entry Draft. Kotalík finished the season in Edmonton before being signed as a free agent by the New York Rangers on July 9, 2009 to a three-year, $9 million contract. Due to his lack of goal scoring production, which he was expected to bring and being a healthy scratch for numerous games due to his lack in scoring, he was traded on February 1, 2010 to the Calgary Flames along with Christopher Higgins in exchange for Olli Jokinen and Brandon Prust.
