The Essex Olympian Football League is a football competition based in England, founded in the 1966–67 season. It has a total of six senior divisions and one under 21 division. The Premier Division sits at step 7 (or level 11) of the National League System and it is a feeder to Division One South of the Eastern Counties Football League. Between 1986 and 2005, the league was known as the Essex Intermediate League.

Clubs to progress up the pyramid from the league include Billericay Town, Brentwood Town, Bowers United, Sawbridgeworth Town, Burnham Ramblers, Hullbridge Sports and Great Wakering Rovers.

The clubs that finish in the top three of the Colchester & East Essex League, Romford & District League or the Southend Borough & District Combination can apply to join the lowest level of the Essex Olympian League.

In 1966, the Essex Olympian Football League was founded, following a meeting at the Saracens Head pub in Chelmsford. The first league constitution consisted of Basildon & Pitsea, Billericay Town, Bishop's Stortford Swifts, Bowers United, Burnham Ramblers, Collier Row, Dorstel Press, Dunmow, Little Waltham, Old Chelmsfordians and Sawbridgeworth, with Burnham Ramblers winning the first edition of the Essex Olympian League, finishing four points above Little Waltham.^[1] Little Waltham left the league at the end of the inaugural 1966–67 season, with British Mathews, Critalls, Essex County Council Staff and Manor Athletic all joining to take the constitution up to 16 clubs.^[2] In 1981, a Second Division was added with eight clubs (Baddow Royals, Basildon Sports, Caribbean International Sports, Chigwell Villa, Civil Service Olympian, Cossor Sports, Ekco and Rayleigh Athletic) joining the league system.^[3]

In 1986, the league was renamed to the Essex Intermediate League,^[4] adding a Division Three three years later.^[5]

In 2005, the league renamed itself back to its original Essex Olympian League name.^[6] In 2008, Takeley moved up the pyramid into the Essex Senior League. Before then the Olympian League had not sent a club to the Essex Senior League for over a decade, causing the Essex Senior League to look elsewhere in Essex for new member clubs, including lower leagues and leagues outside the National League System such as the now-defunct Essex Business Houses Football League. Clubs from this league have previously been able to jump straight into the Essex Senior League due to the facilities at which they play, not where they finished in the Essex Business Houses League.^[7] The following year, in 2009, a Division Three was added, taking the number of leagues administered by the Essex Olympian League up to four.^[8] In 2015, two more leagues were added to the system, being named Division Four and Division Five.^[9] In 2017, The Football Association announced a step 6 (level 10) division for Essex and East Anglia in the Eastern Counties Football League to start playing in the 2018–19 season, meaning the Essex Olympian League would drop to step 7 in Non-league.^[10] In March 2020, as a result of the COVID-19 pandemic, the Football Association announced all leagues from step 3 to 7 on the National League System would be cancelled, with all results being expunged.^[11] In November 2020, the Essex Olympian League was suspended, owing to a second wave of COVID-19 in the United Kingdom.^[12] The league was eventually resumed in April 2021, becoming one of the only leagues in England to resume play after the suspension in November 2020. Buckhurst Hill were promoted at the end of the 2020–21 season, after winning the Premier Division, gaining promotion to the Eastern Counties League Division One South.^[13][14]

The league has 64 teams spread over five divisions for the 2023–24 season:
