We present a near-infrared (NIR) imaging study of barred low surfacebrightness (LSB) galaxies using the TIFR near-infrared Spectrometer and Imager(TIRSPEC). LSB galaxies are dark matter dominated, late type spirals that havelow luminosity stellar disks but large neutral hydrogen (HI) gas disks. UsingSDSS images of a very large sample of LSB galaxies derived from the literature,we found that the barred fraction is only 8.3%. We imaged twenty five barredLSB galaxies in the J, H, K$_S$ wavebands and twenty nine in the K$_S$ band.Most of the bars are much brighter than their stellar disks, which appear to bevery diffuse. Our image analysis gives deprojected mean bar sizes of$R_{b}/R_{25}$ = 0.40 and ellipticities $e$ $\approx$ 0.45, which are similarto bars in high surface brightness galaxies. Thus, although bars are rare inLSB galaxies, they appear to be just as strong as bars found in normalgalaxies. There is no correlation of $R_{b}/R_{25}$ or $e$ with the relative HIor stellar masses of the galaxies. In the (J-K$_S$) color images most of thebars have no significant color gradient which indicates that their stellarpopulation is uniformly distributed and confirms that they have low dustcontent.
