Where to Find Redstone Dust in Minecraft

All Overworld biomes (underground) is the one place tied to Redstone Dust, so that is where a trip for Redstone Dust goes. The height that matters for Redstone Dust is the Y -64 to 16, peaks at Y -59 range, and a tunnel at that level beats a random staircase down. Redstone ore generates in the same layers as diamond, peaking at Y -59. Each ore block drops 4-5 Redstone Dust (more with Fortune). In total, Redstone Dust can reach your inventory through mining or smelting it from its raw form, collecting it as a mob drop, looting it from generated structure chests, and trading with the right villager, so you can pick whichever path your current world makes easiest.

The quickest way to Redstone Dust is the obvious one, and it is efficient enough: mine Redstone Ore with an iron pickaxe or better. Much more common than diamond ore at the same Y-levels. Witches drop up to 6 Redstone Dust; they spawn in Witch Huts (Swamp biome) or during raids. Looting is worth the enchantment here: it lifts the number of Redstone Dust you get per kill at every level, and a farm built around the spawn point keeps them coming without you going out to look again. With 64 Redstone Dust to a slot, a chest holds 1728 of them and a double chest 3456, which is more than most builds will ever ask of you. Before you plan a trip around Redstone Dust, note this on the version side: Distribution changed in 1.18 to match new world depth. Once you have Redstone Dust, it earns its place in the kind of automated farms, hidden doors, and timing circuits that redstone makes possible, so it is worth keeping a few crafted and ready in your storage.

Redstone Repeater, Redstone Comparator, Piston, and Observer come up in the same trips as Redstone Dust, whether through the same biome, the same chest or the same recipe. Stats, durability and the grid for Redstone Dust sit on its own item page.
