Yes, there are. Neutrinos are considerably less massive than electrons (which themselves are considerably less massive than protons and neutrons), and photons have no rest mass at all.
Electron!
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
A proton and neutron are both composed of three quarks. An electron is a fundamental particle and is not composed of smaller particles.
the electron is the smallest in terms of mass. 9.11E-31kg/electron 1.67E-27kg/neutron 1.67E-27kg/proton

It really depends what particle you are comparing it to. Compared with the neutron and proton: The electron has a much smaller mass - roughly 2000 times smaller than the neutron or proton. As far as we know, the electron is a truly elementary particle. Protons and neutrons are made up of smaller particles (the quarks). The electron has a negative charge, the proton a positive charge, and the neutron is electrically neutral.
an electron is much lighter than a proton or neutron.
The proton mass is about 2,000 times greater than the electron mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
