We have carried out a new , near-infrared speckle imaging survey of 19 members of the young stellar population in the nearby ( d = 140 pc ) , \rho 
Ophiuchi cloud core .
Results for four binary and one newly discovered triple system are reported .
Data for all known multiple systems among the pre-main-sequence population of \rho Oph are tabulated .
We define a restricted binary fraction F _ { b,r } and a restricted companion fraction F _ { c,r } as counting only those systems most detectable in the present and previous high-resolution near-infrared imaging surveys , having separations between 0.″1 and \sim 1.″1 and K-band magnitude differences \Delta K < 3 .
Analysis of all the available multiplicity data results in updated values of F _ { b,r } = 24 % \pm 11 % and F _ { c,r } = 24 % \pm 11 % for the Ophiuchus pre-main-sequence population .
These values are consistent with the values in the Taurus star-forming region , and F _ { c,r } is in excess by a factor of 2 relative to the Main Sequence at the 1 \sigma level .
