The current study has investigated the effect of a mobile-assisted language learning (MALL) program on EFL students' critical reading skills. The study followed a quasi-experimental one group design. The study participants were 40 third-year EFL majors at Faculty of Education, Suez University during the second semester of 2017/2018. A pre/posttest was prepared by the researcher in order to measure participants' critical reading skills. At the beginning of the experiment, the participants were pretested. After the administration of the experiment for three months, the participants were post-tested. A paired samples t-test revealed that a statistically significant difference existed between the mean score of the pretest and that of the posttest (t=14.807, p < 0.05) in favor of the posttest. This result indicated that the treatment program had a good impact on developing EFL critical reading skills of the study participants. It was concluded that mobile learning had a significant effect on the third-year EFL majors' critical reading skills. The study therefore recommends mobile learning to be incorporated in EFL college reading courses
