   <hidden TTP98-02  Renormalizing Heavy Quark Effective Theory at O(1/m_Q^3) > We present a calculation of the renormalized HQET Lagrangian
 at order O(1/m_Q^3) in the one particle sector. 
 The anomalous dimensions 
 of local operators and
 time ordered products of dimension 7 contributing at this
 order are calculated in the one loop approximation.
 We show that a careful treatment of the time ordered
 products is necessary to arrive at a gauge independent 
 renormalized lagrangian. 
 Our result sets the stage for an investigation of reparametrization
 invariance at O(1/m_Q^3).
