An '''up smash''' (abbreviated '''u-smash''') ({{ja|上スマッシュ攻撃|Ue sumasshu kōgeki}}, ''Up/upper/above smash attack'') is a [[smash attack]] performed by any character by tapping the control stick upward and pressing A, or, outside of ''[[Melee]]'s'' single player modes, by pressing up on the [[C-Stick]].

Since ''Super Smash Bros. Melee'', all smash attacks can be charged by holding down the A button for up to one second, multiplying [[damage]] and [[knockback]] by up to 1.4. In ''Ultimate'', these charges can be held for up to 3 seconds (or 180 frames), but the attack stops increasing in strength after the 1-second mark.

Up smashes have more flexibility than [[forward smash]]es and [[down smash]]es in terms of when they can be used. A [[jump]] [[jump-canceling|may be canceled]] into an up smash, enabling it to be used [[out of shield]] immediately and during any part of a character's [[dash]] animation, except the skidding animation when they stop running. From ''Brawl'' onwards, jump-canceling to perform a running up smash is unnecessary, and the turn-around animation can be jump-canceled into a reversed up smash. In ''Ultimate'', jump-canceling is not required for up smashes out of shield, and can now be done instantly.

|[[Banjo]] & [[Kazooie]]||Performs the Bill Drill; Banjo spins on the ground while Kazooie jabs upward with her beak.

|[[Diddy Kong]]||Performs a pair of spinning punches leading straight into a jumping uppercut as he completes the spin.

|[[Dr. Mario]]||Plants his feet and headbutts strongly above himself from back to front. His head is granted intangibility for a short while

|[[Greninja]]||Jabs two water blades upwards in a forwards grip, then transitions to reverse grip while slashing them in downward arcs for a second hit.

|[[Little Mac]]||Crouches briefly before throwing a fierce swinging-inwards uppercut. There is a sweetspot on frame 1 that has a flame effect

|[[Mega Man]]||Transforms both hands into electrodes and touches them together above himself, releasing a large electric spark.

|[[Wario]]||{{GameIcon|SSBB}} Inflates his head and spins around to strike upwards with it multiple times.<br/>{{GameIcon|SSB4}}{{GameIcon|SSBU}} Inflates his head and performs a headbutt.

*From ''Melee'' onwards, but not in ''Smash 4'', [[Ness]]'s up smash can hit opponents while charging as the yo-yo comes to rest on the stage in front of him. This is especially dangerous in ''Ultimate'', where the yo-yo can fall down and hang off of ledges and hits multiple times (it cannot be charged off ledges in ''Melee'' or ''Brawl''), allowing it to lead into the attack proper. It is the only up smash to have a hitbox while charging. Its power does not increase in ''Melee'' or ''Brawl'' if charged but it does in later games. Ness's similarly-functioning [[down smash]] is the only down smash to have such a distinction, while [[Corrin]] possesses the only such [[forward smash]].

*[[Bowser]]'s up smash has protection on his shell during his attack – in ''Melee'' it is [[intangible]], but from ''Brawl'' onwards it is fully [[invincible]] – which makes the attack dangerous to trade with, especially from above.  

*[[Mr. Game & Watch]]'s up smash grants head invincibility while its hitbox is active (although in ''Smash 4'', it gains intangibility much sooner), and its speed makes it notoriously difficult to intercept.  

*[[Snake]]'s up smash has a number of unique properties. For one, the charging interval begins after Snake slams the mortar down in front of himself, making it the only smash attack to have a hitbox before it starts charging. It is the only up smash to be a [[projectile]]. Charging the attack also has no effect on the damage or knockback of the projectile, but instead greatly increases the velocity at which it is launched, and thus the height it reaches. The attack is also notable in ''Brawl'' for enabling the furthest-traveling [[DACUS]] in the game.

*[[Inkling]]'s up smash covers opponents in [[ink]].

*[[King K. Rool]]'s up smash, after his initial hop, protects him for a handful of frames with his characteristic [[Belly Super Armor]]. It also has a small hitbox as he begins to fall down which [[spike]]s, which makes it one of only three smash attacks to spike – the others being a sourspot on [[Roy]]'s up smash in ''Melee'', and [[Bayonetta]]'s down smash.

*Throughout the series, but especially in ''Melee'', [[Fox]]'s up smash has been considered especially effective due to its high power and near-instant startup.

*[[Palutena]]'s up smash is notable for having the highest vertical range of any non-projectile attack in the series. In Ultimate, it is notorious for its long duration being able to punish dodges, landings, sidesteps, and edge options with excellent power.

*In ''Ultimate'', [[Zero Suit Samus]]'s up smash is a reliable combo starter at low to mid porcents, leading into all of her aerials except down air, while still possesing respectable kill power at high porcents. This combined with the move's long vertical range, long lasting hitbox and rather low endlag make it commonly considered among the best up smashes in the game.
