Special Herbs, Vol. 4 is an album of instrumental works released by MF Doom under the Metal Fingers moniker, the fourth part of his Special Herbs series. Following the pattern set by previous installments of the series, each track is named for a herb or similar flora.

The album's title is slightly misleading, in that it is not an entirely new volume: the third installment in the Metal Fingers series, Special Herbs, Vol. 3, appears again here as the last eight tracks of Vol. 4. For this reason, the album is also commonly known as Special Herbs, Vols. 3 & 4. The difference in record labels on which the two albums were released explains this quirk, similar to the earlier inclusion of Vol. 1 as the first part of Vol. 2.
