This research aims to describe the characteristics and analyze the validity and feasibility of the Histology Atlas. This type of research is the development of the Sugiyono model. The research procedures are: 1. Identification of potentials and problems 2. Data collection 3. Product design 4. Product validation 5. Product revision 6. Small scale trial 7. Product revision 8. Final Histology Atlas. The research subjects were students and biology teachers. Instruments in the form of media and materials validity questionnaires, teacher and students response questionnaires. The results show that the characteristics of the Histology Atlas are composed of simple to complex tissue, and contain color images with captions. The results of media validity got a percentage of 82.69% (very valid) and material validity got a percentage of 93.18% (very valid). Atlas feasibility test with the teacher's response questionnaire got a percentage of 92.50% (very feasible) and based on the student response questionnaire got a percentage of 84.63% (very feasible). This research can be concluded that the characteristics of the Histology Atlas are composed of simple to complex tissue, the Histological Atlas is also valid and feasible to be used as a student learning media on animal tissue material.
