The invention discloses a railway steel rail straightness measuring instrument which comprises a rack, a driving part, a measuring part and a positioning adjusting part. The rack comprises a cushion block making contact with a steel rail, the cushion block is fixedly connected with the bottom plate, end plates are installed at the two ends of the rack, a linear guide rail is arranged between the two end plates, and the driving component can drive the measuring component to move along the linear guide rail. The measuring part comprises a laser displacement sensor which is used for collecting height information of the steel rail; the positioning adjusting part is used for adjusting the position of the measuring part on the steel rail during detection. The invention further discloses a steel rail straightness measuring method, the detection position is adjusted by rotating the adjusting block, the laser displacement sensor is driven by the synchronous pulley to conduct linear displacement and collect height information, and dynamic detection of the steel rail straightness is achieved. According to the invention, the steel rail straightness detection speed and precision can be effectively improved; railway steel rail detection scene requirements of short-distance lines, short operation window periods and the like are met, and the detection efficiency and precision are improved.
