  We present an atlas of starburst galaxy emission lines spanning 10 orders of
magnitude in ionizing flux and 7 orders of magnitude in hydrogen number
density. Coupling SEDs from Starburst99 with photoionization calculations from
Cloudy, we track 96 emission lines from 977 {\AA} to 205 m which are common to
nebular regions, have been observed in H II regions, and serve as useful
diagnostic lines. Each simulation grid displays equivalent widths and contains
~1.5x10$^4$ photoionization models calculated by supplying a spectral energy
distribution, chemical abundances, dust content, and gas metallicity (ranging
from 0.2 Z$\odot$ to 5.0 Z$\odot$). Our simulations will prove useful in
starburst emission line data analysis, especially regarding local starburst
galaxies that show high ionization emission lines. One sample application of
our atlas predicts that C IV $\lambda$1549 will serve as a useful diagnostic
emission line of vigorous star formation for coming James Webb Space Telescope
observations predicting a peak equivalent width of approximately 316 {\AA}.
