Yes. Dreamscarred Press has some very popular psychic classes and content that are included on d20pfsrd as well as in their third party books. You'll see it if you scroll down to alternate rule systems and use the Psionics heading. That site should also show a few other third party options under the same Alternate Rule Systems section as well as both Mythic Adventures and Occult Adventures which are official Paizo content.
Paizo did come out with their own psychic magic and classes in Pathfinder 1e, under the Occult Adventures stuff, but it very clearly wasn't as much of a focus as the Dreamscarred Press version of psionics since most of the Occult class versions boil down to "this is basically an existing magic class like Wizard but with class features gutted out for a gimmick like summoning a themed ghost."
