Oud-Leusden is a hamlet in the Dutch province of Utrecht.

It is a part of the municipality of Leusden, and lies about 4 km south of Amersfoort.

The name is known from the year 777,[3] when villa Lisaduna was a large farm complex with defences.

In the nineteenth century, most of the churchgoing population lived in the nearby village of Leusbroek (now Leusden-Zuid), and the church was replaced with a new one in Leusbroek, and demolished in 1828.

[4] Oud-Leusden is not a statistical entity,[5] and the postal authorities have placed it under Leusden.
