Anguilcourt-le-Sart is a commune in the department of Aisne in the Hauts-de-France region of northern France.

On 19 May 1983, 41 barrels of highly toxic chemical waste (dioxin-based), originating from the Seveso disaster, were found in an unused abattoir in Anguilcourt-le-Sart.

The barrels, which had been illegally abandoned here by a transport contractor, were transferred the same evening to a military base near Sissonne.

The D643 road also enters the commune from Achery in the west through the village and continuing east to Nouvion-le-Comte.
