Cis-bookend and bun is a 14-cell strict still life consisting of a bookend and a bun stabilising each other. It is one of seven ways in which a bookend and a bun can be arranged to create a still life, and one of the six which have two separate islands (see bookend and bun family below).

It is the 68th most common still life on Adam P. Goucher's Catagolue, being less common than tub with long tail but more common than hook with tail. It is the 11th most common still life with 14 cells, being less common than trans-bookend and bun but more common than trans-rotated bun.
All strict still lifes with a population of 21 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
