The Drumcree conflict or Drumcree standoff is a dispute over yearly parades in the town of Portadown, Northern Ireland. The town is mainly Protestant and hosts numerous Protestant marches each summer, but has a significant Catholic minority. The Orange Order insists that it should be allowed to march its traditional route to and from Drumcree Church on the Sunday before the Twelfth of July. However, most of this route is through the mainly Catholic/Irish nationalist part of town. The residents, who see the march as sectarian, triumphalist and supremacist, have sought to ban it from their area. The Orangemen see this as an attack on their traditions; they had marched the route since 1807, when the area was mostly farmland.

Parades are a prominent cultural feature of Northern Ireland. The overwhelming majority of parades are held by Ulster Protestant, unionist or Ulster loyalist groups, but some Irish nationalist, republican and non-political groups also parade. Due to longstanding controversy surrounding the contentious nature of some parades, a quasi-judicial public body — the Parades Commission — exists to place conditions and settle disputes. Although not all parading groups recognise the Commission's authority, its decisions are legally binding.
