  We present a tachyonic field inflationary model in a teleparallel framework.
We show that tachyonic coupled with the f(T) gravity model can describe the
inflation era in which f(T) is an arbitrary function of torsion scalar T. For
this purpose, dynamical behavior of the tachyonic field in different potentials
is studied, it is shown that the tachyonic field with these potentials can be
an effective candidate for inflation. Then, we discuss slow-roll conditions and
show that by the appropriate choice of the parameters, the inflation era can be
explained via this model. Finally, we argue that our model not only satisfies
the result of BICEP2, Keck Array and Plank for the upper limit of $r < .012$
but also, the obtained value for spectral index $n_{s}$ is compatible with the
results of Plank and also Plank + WMAP + HighL + BAO at the 68% confidence
level.
