The 2003–04 Kent Football League season (known as the Go Travel Kent League for sponsorship reasons) was the 38th in the history of Kent Football League a football competition in England.
The League structure comprised three divisions: a Premier Division together with a Reserves Section comprising newly formed Divisions One and Two – the latter two made from teams featured in previous seasons Division One North and Division One South, with the six highest ranked teams from each division from the previous season placed in the new Division One and the remaining clubs into Division Two. Reserves teams were not permitted in the Premier Division. Additionally there were two league cup competitions: the Challenge Cup for the Premier Division clubs and another for the teams in the two divisions of the Reserves Section.
The 2003–04 Kent Football League Challenge Cup was won by Thamesmead Town.
The competition was contested by the 17 teams from the Premier Division, following a preliminary round there were four further rounds: the first two a single match knock-out followed by the semis-finals on an aggregate basis (home and away matches) and the final match played on a neutral ground (at Folkestone Invicta F.C. this season).
The letter "R" following team names indicates a club’s reserves team.
The 2003–04 Reserves Section comprised two new divisions with promotion and relegation possible between them. They were formed from the previous seasons Division One North and Division One South, with the six highest ranked teams from each division from the previous season placed in the new Division One and the remaining clubs into Division Two. Promotion from the Reserves Section into the Premier Division was not permitted. There was a single League Cup competition for all teams in the section.
At the end of the season champions Corinthian and runners-up Dover Athletic R resigned from the league – the former were the only non-reserves team to have won a division in the Reserves Section.
