Two reservoirs of superfluid helium can be weakly coupled together to form a neutral matter analog of superconducting Josephson junctions. In this chapter, we present an overview of the development of the field of Josephson effects in superfluid helium, reviewing both the experimental and theoretical milestones that led to our current understanding. We discuss the physics of these systems with emphasis on the quantum oscillations that result from varying the coupling strength. We review the principles of superfluid helium quantum interference devices (SHeQUID) and some novel fundamental applications of this new technology.
