We present the magnetic penetration depth [lambda](T) in two laser ablated YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] thin films, determined by the two-coil method. The slope of 1/[lambda][sup 2](T) near T[sub c], the only exactly measurable quantity, extrapolates to 930[Angstrom] at T=0, which compares well with 830[Angstrom] in the high quality single crystal recently reported by Hardy et al., and which exhibited a linear T dependence at low T. For T [lt] 30K, we find [lambda](T)/[lambda](0)[minus]1 = a(T/T[sub c])[sup 2] where a=0.5.
