  We investigate one-dimensional Helmholtz solitons with nonlocal nonlinearity.
We show an exact analytical solution to the nonlocal nonlinear nonparaxial
propagation equation in the cases of high and weak nonlocality. We also
numerically find that the degree of nonlocality can affect the width of
nonlocal Helmholtz soliton beams, but have no effect on their stability.
Contrarily, nonparaxiality can affect their stability, but have no effect on
their width.
