Karl Kruszelnicki AM /krʊʃəlnɪtskiː/ (born 20 March 1948), often referred to as "Dr Karl", is a well-known Australian science communicator and populariser, who is known as an author and science commentator on Australian radio and television.

Kruszelnicki is the Julius Sumner Miller Fellow in the Science Foundation for Physics at the School of Physics, University of Sydney.

Kruszelnicki's family immigrated to Australia when he was two years of age. The family were tenanted at the migrant camp in Bonegilla, Victoria, for the first three years before they settled in the city of Wollongong, New South Wales, where he grew up. After high school, his first job was as a ditch digger in the summer between the end of high school and the start of university, using pick and shovel to dig and lay sewerage pipes in the Wollongong suburb of Dapto.

After university, Kruszelnicki's first job as a physicist was working for a steel works in his home town of Wollongong where he had to test the strength of steel made for use in Melbourne's West Gate Bridge, which was under construction at that time. Kruszelnicki designed a machine to test the steel but its results suggested that the steel did not meet specifications. His boss at the time asked him to recheck the results but when the steel continually failed to meet the specifications his boss asked him to fake the data. Kruszelnicki refused and eventually quit. (The West Gate Bridge collapsed during construction but the fault was found to have occurred due to structural failure not due to the quality of the steel used.)
