Endoplasmic reticulum (ER) stress, a common cellular stress response, is closely related to the activation of autophagy that is an important and evolutionarily conserved mechanism for maintaining cellular homeostasis. Autophagy induced by ER stress mainly includes the ER stress‐mediated autophagy and ER‐phagy. The ER stress‐mediated autophagy is characterized by the generation of autophagosomes that include worn‐out proteins, protein aggregates, and damaged organelles. While the autophagosomes of ER‐phagy selectively include ER membranes, and the double membranes also derive, at least in part, from the ER. The signaling pathways of IRE1α, PERK, ATF6, and Ca2+ are necessary for the activation of ER stress‐mediated autophagy, while the receptor‐mediated selective ER‐phagy degrades the ER is Atg40/FAM134B. The ER stress‐mediated autophagy and ER‐phagy not only have differences, but also have connections. The activation of ER‐phagy requires the core autophagy machinery, and the ER‐phagy may be a branch of ER stress‐mediated autophagy that selectively targets the ER. However, the determined factors that control the changeover switch between ER stress‐mediated autophagy and ER‐phagy are largely obscure, which may be associated with the type of cells and the extent of stimulation. This review summarized the crosstalk between ER stress‐mediated autophagy and ER‐phagy and their signaling networks. Additionally, we discussed the possible factors that influence the type of autophagy induced by ER stress. Under ER stress condition, the ER stress‐mediated autophagy and ER‐phagy can be activated, and both involved in UPR and the core autophagy machinery. However, the determined factors that control the changeover switch between ER stress‐mediated autophagy and ER‐phagy, are unclear. And we speculate that the type of cells and the extent of stimulation may be associated with the type of autophagy induced by ER stress.
