Abstract: A holder for supporting an umbrella relative to a golf cart. The inventive device includes a mounting assembly for securing to a golf cart. The mounting assembly includes an elongated base member with a hook at one end to engage a wire basket of the golf cart; and a channel receiver on the lower surface of the base member to accept the seat supporting rail of the golf cart when the holder is pivoted to a horizontal position. An adjustable support assembly is pivotally mounted to the bifurcated second end of the mounting assembly for engaging a center pole of an umbrella to support the umbrella relative to the golf cart. The support assembly includes an elongated support stanchion; a mounting post coupled to the support stanchion; at least one strap secured to the mounting post, the distal ends of the straps having fasteners to fasten about the umbrella. The support assembly is angularly adjustable using a fastener and wing nut directed through the furcations of the base member.
