To investigate the creep behavior of hybrid fiber-reinforced concrete under coupled temperature and load conditions, compression creep tests were conducted on steel fiber and polypropylene fiber-reinforced concrete at temperatures ranging from 20 °C to 800 °C. The test variables included temperature, load level, heating rate, concrete strength, and the presence of fibers in the concrete. The results showed that transient creep strain （ε _trc) accounted for a significant proportion of the total strain. The temperature range and stress level had a significant impact on ε _trc, especially at temperatures above 500 °C and stress levels above 40%. When the target temperature was constant and the total ε _trc was fixed, the heating rate was positively correlated with the rate of ε _trc increase. Adding steel fibers to normal-strength concrete could slightly reduce the ε _trc of the concrete, while incorporating polypropylene fibers into high-strength concrete significantly increased the ε _trc.
