We calculated widths and shifts due to collisions with electrons, protons, and He II ions for 66 multiplets of neutral boron, using the semiclassical perturbation theory. The range of temperatures is from 2500 to 50 000 K and electron density values are within the range 10¹¹-10¹⁹ cm^-3. The obtained Stark broadening parameters have been compared to other theoretical and experimental results.
