Abstract: The cosmological parameters that I will emphasize are the Hubble parameter H0 ident 100 h km s-1 Mpc-1, the age of the universe t0, the average matter density Omegam, the baryonic matter density Omegab, the neutrino density Omeganu, and the cosmological constant OmegaLambda. The evidence currently favors t0 approx 13 Gyr, h approx 0.65, Omegam approx 0.3, OmegaLambda approx 0.7.
