We present the first angular clustering measurement of ultraviolet-selected galaxies at low redshift ( $z \approx 0.1$) using data from the FOCA survey. We measure the galaxy autocorrelation function $\omega(\theta)$ from three separate fields with $m_{\rm UV} <20.25$ (AB). Assuming $\omega(\theta) = A_\omega
\theta^{-\delta}$ , we obtain $A_\omega = 2.9^{+1.9}_{-1.2} \times 10^{-2}$ and $\delta=0.53^{+0.23}_{-0.26}$, as a best fit to the data, which yields a correlation length r0 = 3.2+0.8-2.3 h-1 Mpc. This estimate is formally lower than those obtained from optically selected $L_\star$ galaxy samples, although the difference is within errors.
