  We show how to double-copy Heavy Quark Effective Theory (HQET) to Heavy Black
Hole Effective Theory (HBET) for spin $s\leq 1$. In particular, the double copy
of spin-$s$ HQET with scalar QCD produces spin-$s$ HBET, while the double copy
of spin-1/2 HQET with itself gives spin-1 HBET. Finally, we present novel
all-order-in-mass Lagrangians for spin-1 heavy particles.
