Pain lands is the term that typically refer to the land cycles first printed in Ice Age and Apocalypse. However, the term can be applied to every land, which deals "pain" damage to you every time you tap it for colored mana.
Original pain lands
The lands providing allied colors were printed originally in Ice Age, those providing enemy colors in Apocalypse. These lands were first referred to as pain lands, even though City of Brass was printed earlier. The former were reprinted in Fifth Edition, Sixth Edition, and Seventh Edition, the latter in Magic 2015 and Magic Origins. The complete cycle of ten lands were reprinted in Ninth Edition and Tenth Edition.
In addition, there exists the Grand Coliseum, which can tap for mana of any color.

Other pain lands
- Ancient Tomb can only be tapped for for 2 damage.
- City of Brass can't tap for colorless, but can produce any color. The damage is a separate ability, which lets it be exploited through land-tapping effects.
- Murmuring Bosk (/) has the basic land type Forest. It can be tapped for (instead of ) without taking damage.
- Tarnished Citadel can produce any color for 3 damage, but can also be tapped for .
- Tomb of Urami produces only for 1 damage if an Ogre is not controlled, but can also generate a 5/5 Flying Demon Spirit token at the cost of and all one's lands.
Most pain lands deal damage to you when activating. This damage is a separate effect and can be prevented without losing the mana. However, some pain lands require you to pay the life, before getting the mana. The Deserts and the Horizon lands follow this template, along with a few others:
- Corrupted Crossroads can produce any color by paying 1 life, which can only be spent to cast Devoid spells.
- Mana Confluence can't tap for colorless but can produce any color by paying 1 life.
- Spire of Industry can tap for colorless for free, or produce any color by 1 life given the player controls an artifact.
The following lands from Kamigawa are three colorless-producing, life-payment lands that all enter tapped:
- Boseiju, Who Shelters All's mana costs 2 life, and instant or sorcery spells that were cast with this mana can't be countered.
- Hall of the Bandit Lord's mana costs 3 life, and creatures cast with this mana gain haste.
- Untaidake, the Cloud Keeper produces at the cost of 2 life, and can only cast legendary spells.
