The invention discloses a fan support and a floor fan. The fan support comprises upper support bodies (1) and at least two lower support bodies. The lower support bodies are rotationally arranged relative to the upper support bodies (1) and located on the two sides of the midperpendicular of the upper support bodies (1) respectively when supporting is formed. The upper support bodies (1) are provided with stopping-blocking structures (2) which are used for stopping and blocking the lower support bodies in supporting positions. The lower support bodies are provided with the supporting positions and folding positions. The supporting positions are matched with the stopping-blocking structures (2) to support the upper support bodies (1). The folding positions are overturned relative to the upper support bodies (1) and folded with the upper support bodies (1). According to the fan support, the problems that in the prior art, a fan support is complex in structure and inconvenient to install and operate can be solved.
