In flat spacetime, a number of “special” scalar field theories have been identified which possess shift symmetries, non-renormalization theorems and enhanced soft limits.  In this talk I’ll present the construction of the de Sitter analogues of these theories and I’ll discuss their curious properties.  I’ll also discuss the generalization to higher spin.
