The invention provides a bicycle saddle, a saddle forming die and a saddle forming process, and solves the problem that an existing saddle is short in service life. According to the bicycle saddle, the bicycle saddle comprises a memory foam layer, a high-resilience cotton layer and a saddle bottom shell which are sequentially arranged from top to bottom, a concave cavity matched with the memory foam layer in shape and size is formed in the top wall of the high-resilience cotton layer, and the inner diameter of the concave cavity at the cavity opening is gradually decreased from inside to outside; the memory foam layer is integrally formed in the concave cavity in an injection molding manner, and the upper side of the memory foam layer extends out of the concave cavity; the die comprises a female die, a first male die and a second male die, a first cavity used for forming a high-resilience cotton layer is formed between the first male die and the female die, and a second cavity used for forming a memory cotton layer is formed between the second male die and the female die. The process comprises the following steps: A, forming the memory foam layer; B, forming a high-resilience cotton layer; and C, trimming. The service life is long.
