In this research paper, we develop the geometrical bearing on Legendrian submanifolds of Sasakian space forms in terms of r-almost Newton-Yamabe Soliton with the potential function ψ: Mn → R. Also, we examine the certain conditions for L-minimal and totally geodesic Legendrian submanifolds of Sasakian space form admitting the r-almost Newton-Yamabe Soliton. Finally, we illustrate some examples based on this study.
