The invention provides a type of all-terrain vehicle seat installation structure; it includes the cab frame and the seat backrest arranged on the frame; the back mounting side of the seat backrest includes the first mounting part and the second mounting part arranged up and down respectively. The first mounting part includes the upper support frame located at the upper end of the frame; the installation hole is arranged on the upper support frame; the installation pin inserted into the installation hole is extended out of the seat backrest. The second mounting part includes the lower support frame located at the lower end of the frame; the lower end of the seat backrest is provided with the installation buckle mounted on the lower support frame. The top of the seat backrest is limited by the installation pin being inserted into the installation hole; the seat backrest is supported by the bottom installation buckle; the top of the seat backrest is limited by the inserting installation structure of the installation pin and the installation hole to avoid the seat backrest moving up and down on the frame, so the stability of the seat installation structure of the all-terrain vehicle is improved. The invention also provides a type of all-terrain vehicle provided with the seat installation structure of the all-terrain vehicle as described above.
