Aghalee (from Irish Achadh Lí ⓘ, meaning 'field of calves') is a village, townland and civil parish in County Antrim, Northern Ireland.

It is three miles from the southeast corner of Lough Neagh on the main road between Lurgan and Antrim and about 13 kilometres west of Lisburn.

The village lies on the steep wooded slopes of Friar's Glen and is beside the now disused Lagan Navigational Canal.

Much of the early development of Aghalee was due to its strategic location beside the Lagan Navigational Canal which opened at the end of the 18th century.

The village became a distribution centre for the surrounding area and developed as an important lock station on the Lagan Navigation, as it was one of the last sizeable settlements before the canal entered Lough Neagh.
