The LSWR 0298 Class or Beattie Well Tank is a class of British steam locomotive. They are 2-4-0WTs, originally built between 1863 and 1875 for use on passenger services in the suburbs of London, but later used on rural services in Southwest England. Out of a total production of 85, two locomotives have been preserved in an operational condition.

In 1850, the LSWR decided that the London suburban passenger services should be operated using small tank locomotives. To determine the most suitable type, Joseph Hamilton Beattie, the LSWR Mechanical Engineer, prepared a series of designs, each of which incorporated one or more differences from the previous class. A small quantity of each were produced. Having chosen the most suitable characteristics, Beattie prepared a standard design of 2-4-0WT and the LSWR began to take delivery of these in 1863.
