Shane Brennan (born January 20, 1957, in Bendigo, Victoria, Australia) is an Australian television writer and producer, best known as the executive producer of the CBS drama ''NCIS'', as well as the creator of the ''NCIS'' spin-off series, ''NCIS: Los Angeles''.

Brennan's other television credits include ''Special Squad'', ''The Flying Doctors'', ''All Together Now'', ''King & Maxwell'', ''State Coroner'', ''Stingers'', ''Flipper'', ''CSI: Miami'', and ''Summerland''. Beginning as a journalist for the Australian Broadcasting Corporation (ABC), by 1981, he had abandoned journalism for television scriptwriting.

From the mid-1990s he worked on American cable shows shot in Australia – of which ''Flipper'' is the only named example in the IMDb. That gave him exposure, friends in the U.S. and an agent. As he said, "I started travelling backwards and forwards for about five years – usually four or five times a year, coming for two or three weeks at a time, doing lots and lots of meetings, all at my expense."

In 2003, Brennan became supervising producer for ''CSI: Miami'', and then went on to succeed Donald P. Bellisario as the showrunner on ''NCIS'', handing the day-to-day showrunner operations over to Gary Glasberg after season 8. He then created and became the showrunner of ''NCIS: Los Angeles'', while remaining an executive producer of ''NCIS'' until the end of the eleventh season. His last credited episode as executive producer of ''NCIS'' was the season 11 finale episode, "Honor Thy Father". In 2011, his production company signed a deal with CBS.

In July 2016, it was announced that Brennan was stepping down as showrunner of ''NCIS: Los Angeles'' and that he was handing the reins over to R. Scott Gemmill. In February 2022, it was announced that Brennan would lead a new ''NCIS: Sydney'' set in Sydney.

Brennan was elected president of the Australian Writers' Guild in January 2019. Provided by Wikipedia
