Tonight is a BBC television current affairs programme that was shown on weekday nights from 1 September 1975 until 5 July 1979 on BBC1.^[1][2] It was initially presented by Sue Lawley, Denis Tuohy and Donald MacCormick and reporters included John Pitman, Richard Kershaw, David Lomax, David Jessel and Michael Delahaye. Michael Bunce was the programme's first editor.^[1] Unlike its predecessor also called Tonight which was shown in the early evening, this programme was generally the last BBC1 programme each evening and appeared at variable times. It took over from the 24 Hours programme, also on BBC1 in late evenings, and ran in the same years as the BBC's Nationwide which was shown early evening.^[1]

Lawley took maternity leave and Ludovic Kennedy and Robin Day, from BBC2's Newsday current affairs series, became new presenters, supported by Melvin Bragg and Barry Norman for arts and cinema topics.^[3][4] Jeremy Paxman became a new presenter.^[5]
