Questions Regarding Trapfinding

[Krell44]

Is there a Trait that gives Trapfinding?

If not, what are the classes available that can gain Trapfinding? Rogue, Investigator....any others? Perhaps some archetypes?

Trap Finder a Campaign trait from Mummy’s Mask.

EDIT: I should say, it allows finding magic traps. It doesn't actually give the trapfinding class ability.

There is also an arcane spell called Aram Zey's Focus (genericized to Trapfinder's Focus at d20pfsrd) that temporarily grants Trapfinding to the caster.

There is the Crypt Breaker archetype for the Alchemist that gets Trapfinding instead of Brew Potion. Not a bad archetype, depending on what you want to do with it. There is also the Trap Breaker archetype, which potentially stacks with Crypt Breaker (depending on how your GM views it...)

The Slayer can take the Trapfinding talent.

barbarian also has it as does the traper ranger

[Diachronos]

No traits that give the actual Trapfinding ability, but as graystone said you can take the Trap Finder trait and get the ability to disable magic traps as if you had trapfinding, as well as getting a +1 to all Disable Device checks.

The Archaeologist bard archetype gets something similar and arguably better at level 2, since it's a flat +1/2 level to ALL Perception and Disable Device checks on top of being able to use Disable Device faster and take 10 at level 6... but you can't disable magic traps with it.

Take both, though, and you're better at trap-breaking than most rogues could ever be.

Nice, and it appears that Cryptbreaker will stack with Grenadier?

Never mind, they both trade out Brew Potion. Thats unfortunate.

The Seeker archetype for Sorcerers or Oracles gives you trapfinding.
I've got an Aether Kineticist 6/Seeker Oracle 1. Mostly for Life Link + Force Ward shenanigans. But picking up Trapfinding to use with Kinetic Finesse to telekinetically disarm traps at range is great. With a 12 Cha, you also get 4 castings of Fallback Strategy per day, which has proven quite useful.

[Melkiador]

To be clear, the archaeologist can disable magical traps at level 6.

[Omnitricks]

Unchained disable device at 10 ranks (assuming you are asking about trapfinding to disable magic traps)
