We develop the covariant string field theory approach to open two-dimensional strings. Upon constructing the vertices, we apply the formalism to calculate the lowest-order contributions to the four- and five-point tachyon-tachyon tree amplitudes. Our results are shown to match the bulk'' amplitude calculations of Bershadsky and Kutasov. In the present approach, the pole structure of the amplitudes becomes manifest, and their origin from the higher string modes becomes transparent.
