A pipe and pump retrieval tool 10 is described for removing a disconnected or "lost" pipe and pump assembly 20 from the bottom 16 of a well 12. The retrieval tool 10 includes elongated body 40 illustrated in FIGS. 2, 6 and 8 extending from a lower end 42 to an upper end 44. A shoulder engaging means 50 is associated with the upper end for receiving and engaging a pipe section and a pipe coupling 28. A retrieval cable 60 connects to the lower end 44 and is threaded through a cable stabilizing means 64 to naturally orient the elongated body 40 at an incline angle with the upper end 44 and lower end 42 sliding along opposite sides of the interior of the well wall 14. A safety cable connecting means 68 is provided to enable the retrieval tool 10 to be removed from the well and disconnected from the pipe and pump assembly 20 should the assembly 20 be stuck at the bottom of the well.
