According to Relational Quantum Mechanics (RQM) the wave function $\psi$ isconsidered neither a concrete physical item evolving in spacetime, nor anobject representing the absolute state of a certain quantum system. In thisinterpretative framework, $\psi$ is defined as a computational device encodingobservers' information; hence, RQM offers a somewhat epistemic view of the wavefunction. This perspective seems to be at odds with the PBR theorem, a formalresult excluding that wave functions represent knowledge of an underlyingreality described by some ontic state. In this paper we argue that RQM is notaffected by the conclusions of PBR's argument; consequently, the allegedinconsistency can be dissolved. To do that, we will thoroughly discuss the veryfoundations of the PBR theorem, i.e. Harrigan and Spekkens' categorization ofontological models, showing that their implicit assumptions about the nature ofthe ontic state are incompatible with the main tenets of RQM. Then, we will askwhether it is possible to derive a relational PBR-type result, answering in thenegative. This conclusion shows some limitations of this theorem not yetdiscussed in the literature.
