High-resolution laser spectroscopy has been performed using a tunable diode laser to measure the hyperfine structure (hfs) and Zeeman shift of two transitions in Y I. The hfs constants $A$ of 89Y were determined for the $4d5s^{2}$ $^{2}D_{3/2}$ and $^{2}D_{5/2}$ levels, and $4d5s5p$ $^{4}F_{3/2}$ and $^{4}F_{5/2}$ levels; the $A$ values of the $^{4}F_{3/2}$ and $^{4}F_{5/2}$ were determined for the first time. Using circular polarizations, the Zeeman spectra were selectively measured and the $g$ factors were determined for the $4d5s5p$ $^{4}F_{3/2}$ and $^{4}F_{5/2}$ levels.
