Rainer (Rai) Weiss (sinh 29 thang 9 nam 1932) la giao su vat ly danh du tai Hoc vien Cong nghe Massachusetts. Ong đuoc biet đen la nguoi đa phat minh ra thiet bi tham do song hap dan bang ky thuat giao thoa laser ma no la co so hoat đong cua cac tram đo luong song hap dan bang giao thoa ke nhu LIGO, GEO600 hoac VIRGO. Rainer Weiss la chu tich Nhom Nghien cuu Khoa hoc cua du an COBE.
Ong đuoc trao giai Nobel Vat ly nam 2017 cung voi Kip Thorne va Barry Barish "cho nhung đong gop quyet đinh cua ho đoi voi LIGO va quan sat song hap dan".


Giao duc va cong tac Rainer Weiss sinh ngay 29 thang 9 nam 1932 tai Berlin, Đuc. Đe tranh khoi cuoc khung hoang kinh te, gia đinh ong ban đau chuyen đen Praha vao cuoi nam 1932, va sau đo đen Hoa Ky vao nam 1938; thoi nien thieu ong o thanh pho New York, noi ong hoc truong tieu hoc Columbia. Ong hoc đai hoc tai MIT, nhan bang cu nhan vat ly nam 1955 va bang tien si nam 1962 duoi su huong dan cua Jerrold Zacharias tai đay. Ong giang day tai Đai hoc Tufts trong cac nam 1960–62, la nguoi nghien cuu hau tien si tai Đai hoc Princeton giai đoan 1962–64, va sau đo đuoc nhan vao MIT nam 1964.


Cac nghien cuu Rainer Weiss đa đong gop vao hai linh vuc nghien cuu vat ly co ban tu luc khai sinh cho toi khi hinh thanh hai nganh lon: nghien cuu cac đac trung cua buc xa phong vi song vu tru, va đo luong truc tiep song hap dan bang phuong phap giao thoa.
Ong đa thuc hien cac phep đo tien phong ve buc xa nen vi song vu tru, roi sau đo la nguoi đong sang lap va chu tich uy ban tu van khoa hoc cua du an tau tham do vi song COBE cua NASA. Nam 2006, cung voi John C. Mather, ong va đoi COBE đa nhan Giai Gruber ve Vu tru hoc.
Weiss la nguoi đa phat minh ra phuong phap giao thoa ke laser đe đo luong truc tiep song hap dan, va la nguoi đong sang lap ra đai quan trac song hap dan LIGO, mot du an do Quy Khoa hoc Quoc gia (NSF) tai tro. Nhung no luc đay thu thach trong khoa hoc thuc nghiem nay la nham thu đuoc hieu biet quan trong ve vat ly o pham vi truong hap dan cuc manh trong Vu tru. Nam 2007, cung voi Ronald Drever, ong đuoc trao Giai Einstein cho nhung đong gop ve đo luong song hap dan.
Ngay 11 thang 2 nam 2016, ong la mot trong so nhung nha khoa hoc cua Nhom Hop tac Khoa hoc LIGO dien giai trong buoi cong bo la Nhom Hop tac Khoa hoc LIGO đa phat hien va đo luong truc tiep đuoc song hap dan ma hai tram quan trac LIGO đa thu đuoc vao ngay 14 thang 9 nam 2015. Sau su kien nay, ong cung voi Ronald Drever va Kip Thorne đa nhan cac giai thuong giai Đot pha trong Vat ly co ban, giai Gruber ve Vu tru hoc va giai Shaw.
