We present a measurement of baryonic acoustic oscillations (BAO) from Lyman-$\alpha$ (Ly$\alpha$) absorption and quasars at an effective redshift $z=2. 33$ using the complete extended Baryonic Oscillation Spectroscopic Survey (eBOSS).

For an operational mode which balances purity and completeness ($p_{\rm min}=0. 28$) we recover a purity of $96. 81\pm0. 39\%$ ($99. 30\pm0. 14\%$ for quasars with $z \geq 2. 1$) and a completeness of $96. 83\pm0. 30\%$ ($98. 42\pm0. 15\%$ for quasars with $z \geq 2. 1$).
