Marks Tey is a village and civil parish in the City of Colchester district of Essex, England; it is located six miles west of Colchester. It is one in a group of villages called The Teys, including Great Tey and Little Tey. At the 2021 census the parish had a population of 2,617.

Marks Tey's main features include a village hall built in 1993 on the fields intersecting the A12 and A120, with an adjacent children's play park and a skateboard park.

There is a small parish hall, used for children's kindergarten and small exhibitions. The hall was almost doubled in size after the extension of the new basketball hall. The hall and gardens also host a monthly artisan event called Marks Tey Market on the fourth Saturday of the month (from March to October).

The village has a parish church, St Andrew's. The church hall is central to the community, hosting 1st Marks Tey Scout Group with Beavers, Cubs and Scouts.

Following the demolition of the Prince of Wales public house, the Red Lion was the only pub serving the village, but this too closed down during the COVID-19 pandemic. In 2001, The Food Company erected their first outlet on the site of the former Prince of Wales, selling speciality foods and drink; however, the business closed in 2017. The premises were refurbished in 2021 and is now a solicitors' firm.

Also located on London Road are a post office, convenience store, fish and chip shop, Indian & Chinese take-aways, a butchers, bakers, hairdressers, a cycle shop, a car supplies shop, a petrol garage and a pharmacy.

Marks Tey Football Club was established in 1998. The home ground is Jubilee Playing Fields in Old London Road, alongside the skateboard park. It currently has one men's Saturday team, one men's Sunday team, one veterans' team, two youth teams and two mini football teams.

In 2016, Marks Tey was light-heatedly named the 'home of English football' based on Google Search trends.
