Introduction: <<理學院>> 清大理學院成立於民國五十二年，現有數學系 (學/碩/博士班)、物理系 (學/碩/博士班) 、化學系 (學/碩/博士班)、天文研究所 (碩/博士班)、統計研究所 (碩/博士班)、理學院學士學位學程 (跨學門雙專長) 及跨院先進光源科技碩/博士學位學程 (理學院為物理組、原子科學院為工科組)。物理系及天文所為一系多所架構，學位學程由各系所支援教師。而國科會1997年於清華成立國家理論科學研究中心 (NCTS)，設有數學組及理論物理組，是我國理論科學研究國際合作之重要窗口，理學院並配合成立理學院數學科學中心。2004年天文所與中研院天文所合作成立高等理論天文物理研究中心 (TIARA)。此外清華為整合基礎科學跨學門大型研究，於2007年成立清華基礎科學研究中心。理學院以美國爾灣加州大學理學院(University of California of Irvine, UCI)為標竿學院，並追求學術卓越，將持續推動跨學門基礎科學教學，進行世界級尖端前沿研究，並關懷社會做出積極正面貢獻。
The College of Science (or CoS) is currently composed of Department of Mathematics, Department of Physics, Department of Chemistry, (all with B.S., M.S. and Ph.D. curricula), Institute of Statistics, (with both M.S. and Ph.D. curricula), Institute of Astronomy (with M.S. curriculum, and Ph.D. curriculum being applied for MOE approval), CoS Bachelor of Science Program (for interdisciplinary double major curriculum) and the M.S. and Ph.D. curricula for Science and Technology of Synchrotron Light Source Program (Physics Division belongs to College of Science, while Engineering & System Science Division belongs to College of Nuclear Science). Institute of Astronomy is made to affiliate under Department of Physics, while all courses and lectures offered by CoS Bachelor of Science Program are administrated by the faculty members of CoS. Concentrating on achieving academic excellence, CoS constantly promote all levels of science education, conducting world-class forefront researches, and engage in activities to push forward our society. Our exemplary models are the related Science Colleges at the University of California, Irvine, California.
