The twenty-second season of British science fiction television series Doctor Who began on 5 January 1985 and ended on 30 March 1985. It opened with the serial Attack of the Cybermen and ended with the serial Revelation of the Daleks. The season returned to the traditional Saturday transmission for the first time since Season 18, but for the first and only time in the series' first run it featured 45-minute episodes in its entirety. During transmission, BBC1 controller Michael Grade announced an 18-month hiatus for the series, partly citing the violence depicted in the stories of the season. John Nathan-Turner produced the series with Eric Saward as script editor.
