{{Infobox set|OGW}}
[[Oath of the Gatewatch]] is the third ''Magic: The Gathering - Puzzle Quest'' set, released in June 2016 in version 1.5 of the game.  The set abbreviation is OGW, and the set icon ([[File:OGW_Symbol.png|x16px|OGW]]) is a stylized split triangular shape with some resemblance to a hedron.

[[Oath of the Gatewatch: Part 1]] and [[Oath of the Gatewatch: Part 2|Part 2]] are 8-node Legacy PvE events released at the same time and featuring elements of the set.

[[Nodes of Power]] is a Legacy PvP event, similarly released.

There are no Oath of the Gatewatch packs given as rewards, because [[#Cards|Oath of the Gatewatch cards]] are only found in [[Battle for Zendikar]] packs, with the exception of one included in the Zendikar Welcome Pack from [[Duel Decks: Zendikar vs Eldrazi]].

[[Ajani Vengeant]] (AJ1), [[Kiora, Master of the Depths]] and [[Sarkhan the Mad]] are [[Planeswalkers]] released around the time of OGW. Like the [[Battle for Zendikar]] Planeswalkers that preceded them, they all have lower than normal mana bonus totals and [[Origins]] cards in their Starting Decks. Mana gains, with one exception, were (temporarily) sorted out in the next sets, [[Shadows over Innistrad]] and its expansion, [[Eldritch Moon]], and non-Origins cards added to EMN's [[Arlinn Kord]].
